Hi, I am trying to save data in .csv, .txt and .xls format. Matlab recommends to use writematrix, writetable or writecell instead of xlswrite. But when I try it these functions are not working, this is the error message that I got when I tried the exact example shown on Matlab page https://uk.mathworks.com/help/matlab/ref/writematrix.html.
"Undefined function or variable 'writematrix'."
the example that I tried is:
M = magic(5);
writematrix(M,'M_tab.txt','Delimiter','tab');

writematrix() was released in r2019a. You are using r2018b which is why that function is not defined.
Here are links to the documentation for specific release. Use the r2018b documentation for your current version of matlab.
