lake_names =[lake_Erie,lake_Huron,lake_Michigan,lake_Ontario,lake_Superior]; now I want to get Matlab to show me the lake names and the corresponding value after it sorts them, is that even possible to do? size depends on the specific operating system and locale. Hi, I have a problem here where I could not display my result of the equation in the text area. How do I insert a variable text string in matlab. range [0,1], for example, [0.4 displayFormula(symstr,old,new) The main function should then display the results as a string containing x, y, and the totals. With respect to suggesting a good resource for learning MATLAB, you shouldn't underestimate the value of the MATLAB documentation. Then assign the string to the text box in the app using. Read this to know why: https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval. Display a matrix and label the columns as Corn, Oats, and Hay. Text object. Your approach is fundamentally flawed because you are storing meta-data in the variable names: trying to access that meta-data will make your code complex, slow, and hard to debug. fixed it myself using: But how do I latex the fonts and also how do I increase its size. Hey MATLAB users, I'm trying to show a numerical value with its unit in the command window. For example, 500 grams or 4.7k Ohms. But when I run the code, I get the error. "m" looks like regular alphabet. If a one line solution is needed, you can use the num2str function to convert the matrix to a character array. https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636700, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636704, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636709, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636710, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636734, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636738, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#answer_346705, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636714, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636718, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636720, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636721, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636725, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636727, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636744, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636777, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636785, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636789, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636801, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636853, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636855, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636859, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636872, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636873, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636881, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_637283, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_637289, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#answer_346706, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#comment_636715, https://www.mathworks.com/matlabcentral/answers/429596-how-do-i-insert-a-variable-text-string-in-matlab-plot#answer_346721. thanks! To display a text in MATLAB, we use disp function which displays the text or value stored in a variable without actually printing the name of the variable. By default, MATLAB supports a subset of TeX markup. Another way used in MATLAB is to type the name of the variable in the command window after the variable is assigned a value; doing this will display the name of the variable also before its value. But I'm trying to sort variables from highest to lowest and I want to get Matlab to print their corresponding variables rather than just giving me numbers. Examples collapse all Display Variable Values Create a variable with numbers and another variable with text. App designer has edit fields that return text and edit fields that return numeric values. How do you get out of a corner when plotting yourself into a corner. Define a string that describes a differential equation.
