How can I load lots of files with a for loop and then multiply them by a vector

1 visualización (últimos 30 días)
Hello all,
I've got three .mat files each with size 100x1
I also have those files in an xlsx format
(variable1_data.xlsx, variable2_data.xlsx, variable3_dta.xlsx)
I want
1. to load them simultaneously with a for loop into my code and
2. to multiply them with a known vector called fr
My code until now is:
for i=1:N
fr = fraction(:,1)/sum(fractions(:,1:N),2) % where fractions is a 100x 3 matrix
for j=1:100
??????? unknown part
At the end I'd like to have a matrix called variable with size 100x1
Any ideas on that?
Many thanks!

Assuming that all the MAT files have same data(let's say "mydata"):
for i=1:N
toLoad = sprintf('variable%d_data.mat',i);
If this does not answer your question, explain what exactly you are looking for

Thank you for your response.
Actually, this not not exactly what I'm looking for, because my fr changes as well within the for loop, but it's close to what I was looking for.
