Choose a web site to get translated content where available and see local events and Making statements based on opinion; back them up with references or personal experience. Couple of choice depending upon just how you want to use it As a function, can retrieve the passed variable name with, so can write something like the following (without any error checking, formatting, etc., etc., etc., )--, % DISPWITHNAME(X) -- Display scalar variable(s) in argument list with name(s), Alternatively, you could capture the list of desired variables from, with an argument list including appropriate wildcard and then iterate over that list having rearranged the order from the default aplphanumeric sort to the desired numeric order by use of the optional indexing array variable returned by. Character thickness, specified as 'normal' or When I run the function on (1,2) I get ans=3 , which means that the other two functions, mxy and dxy, aren't seeing the values of x and y.

Nope, num2str makes it difficult to work. The initial section of how to use disp command show. code as input to disp. D = [ Country, ' is ranked ' , num2str(Rank1), 'th in terms of nominal GDP and ', For geographic axes, the second coordinate is longitude in Hey MATLAB users, I'm trying to show a numerical value with its unit in the command window. and you can always do this: I know how to implement variable legend, but not the text. I've tried using %f where the variables should be and then putting a comma and the variable name at the end as well as: disp ('text ' + variable + 'more text'); matlab disp Share Improve this question The result automatically shows the multiplication being carried out element-wise. To change the font units, use the pixels are independent of your system resolution on Windows and Macintosh systems: On Windows systems, a pixel is 1/96th of an inch.

MathWorks is the leading developer of mathematical computing software for engineers and scientists. By the way can I have a third legend in which there are only two curves? if you have a complex number vector just use: theThingYouWantToShow = roots(someArray); %theThingYouWantToShow is a vector with complex numbers (if you can show this, you can show anything :) (I guess) ), https://www.mathworks.com/matlabcentral/discussions/highlights/134262-new-in-r2021a-capture-disp-output-as-a-string.
