I want to create an output file. I would like my file to contains also one specific string (character) in its name.

My code is:

%A is a matrix (100x1 double)
str='2020'
writematrix(A,'output' str '.xlsx')

But command writematrix shows me error.

Could you please help me?

You need to concatenate the character arrays. Here is one way to do that:

str='2020'
writematrix(A,['output',str,'.xlsx'])

Alternative:

writematrix(A,"output"+str+".xlsx")
