Incrementing file names to run loop commands

Hello

I am trying to write a short script to input some data from a list of files. The file names have a form as followed

Sample_run1_0V_dev.s2p

Sample_run1_5V_dev.s2p

Sample_run1_10V_dev.s2p

and so on

I would like to write a script in a loop format kind of like this

for n=0:5:200

Sample_run1_[n]V = sparameters('Sample_run1_[n]V_dev.s2p')

end

I would like the loop to increment the name of the file by changing just the characters in the brackets which will always be number and they will increment by 5 with each file name.

Currently I am doing this with a command for each file. After I import I then have to process the data which I again do but creating a block that executes the process for each file name but I would like to do this with a loop so I could write the commands once then repeat it by incrementing through the file names.

Thank you for the help

Use sprintf to create your variable names, use arrays to store your data. Don't use numbered variables.

I'm not familiar with the sprintf command or how to use arrays. I'll have to look into that.

V = 0:5:200;
N = numel(V);
C = cell(1,N);
for k = 1:N
    F = sprintf('Sample_run1_%dV_dev.s2p',V(k));
    C{k} = sparameters(F);
end

This is making a little more sense to me. I'll give this a try. Thanks
