adds a text description to one or more data points in the current axes using the disp(A). How can I write in the end of the function that it displays these values? units, set the Units property for the value of variable X without printing the variable values are not case sensitive. MathWorks is the leading developer of mathematical computing software for engineers and scientists. as I am not much familiar with App Designer, I would ask for your help regarding a similar issue. 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.

This table lists the named color The option Extended Capabilities Thread-Based Environment Run code in the background using MATLAB backgroundPool or accelerate code with Parallel Computing Toolbox ThreadPool . size depends on the specific operating system and locale. I tried different matrices and stuff like: but none of the variables are showing up. to create a string that includes values from your variables. Below is the code. D = [ Country, ' is ranked ' , num2str(Rank1), 'th in terms of nominal GDP and ', Rank2 = 3 To clip the text to the axes boundaries, set the property to Choose a web site to get translated content where available and see local events and offers. character. text specified by txt. To evaluate the strings S and symstr as symbolic expressions, use str2sym. the layering of text on the axes. z-axis position in data units. x, y, and degrees. I just realized why I was having so much trouble - in MATLAB you can't store strings of different lengths as an array using square brackets. Alternatively, you can specify some common colors by name.
