For multiline text, use nested cell arrays. You can use the disp () function to display a string in MATLAB. values in this table. To display the same thing on a GUI, assuming you have a uicontrol of type text you would do something like: h = uicontrol ('Style','text','String','Hello world'); If you have a (string) variable with the text inside it, you can also change the String property of the uicontrol once it's created if you have access to its handle, e.g. To learn more, see our tips on writing great answers. Choose a web site to get translated content where available and see local events and How to get Matlab to print both values and variable name values are not case sensitive. scalar, cell array of character vectors, string array, symbolic variable, function, 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. This would be confusing, because readers expect the same number of lines as legend entries. With respect to suggesting a good resource for learning MATLAB, you shouldn't underestimate the value of the MATLAB documentation. range [0,1], for example, [0.4 TeX markup. Just put the name of the variable on the line of code without anything else, no semicolon, etc. code as input to disp. multiple points, specify x and y as For example, text(.5,.5,{'first','second'}). Trying to display text and variable in a single output line. Convert any numeric values to characters using the num2str function. I corrected it. What is the correct way to screw wall and ceiling drywalls? z-axis position in data units. Define a string that represents a quadratic formula with the coefficients a, b, and c.
