Iteratively rename a .txt using writematrix

Hello everybody,

I have created the following array:

substrates={'MgO' 'SiO2' 'W' 'Al2O3' 'Sapphire'};

What I want to do is, after calculating an array within a for loop for each "substrates" element, i=1:length(substrates), save it in .txt using the writematrix function. I have tried something like:

writematrix(matrix,'C:\Users\...\Matrix_',substrates{i},'_Substrate.txt','Delimiter','space')

But it doesn't work, telling me the error that "MgO" is an invalid parameter name.

Any ideas?

If you would like to write into a file with path and name as 'C:\Users\...\Matrix_MgO_Substrate.txt',

you need to concatenate strings horizontally like this:

writematrix(matrix,strcat('C:\Users\...\Matrix_',substrates{i},'_Substrate.txt'),'Delimiter','space')
