your posting style is messy and confusing...
simply displaying error messages is frustrating...
show CSSM a concise snippet of data and ML code of your input and desired output...

Sorry, the code disappeared. Here it is (S_d1.txt, S_d2.txt, etc. are files containing a matrix:

for i = 1:8
s = load([S_d' int2str(i) '.txt']);
f = s.([' S_d' int2str(i)]); % See "dynamic field names"
size(f)

end
%B = rand(10, 3); % Test data
%save('B', [sprintf('FileName%d.mat', j]);
%s=['load S_d' int2str(i) '.txt']
??? Undefined function or variable
'S_d'.

Error in ==> essai_int2str_jan at 3
s = load([S_d' int2str(i)
'.txt']);


and here is the other try I made:

for i = 1:8
s=['load S_d' int2str(i) '.txt']
f = s.([' S_d' int2str(i)]); % See "dynamic field names"
size(f)
end
%B = rand(10, 3); % Test data
%save('B', [sprintf('FileName%d.mat', j]);
%s=['load S_d' int2str(i) '.txt']
??? Attempt to reference field of
non-structure array.

Error in ==> essai_int2str_jan_a at
6
f = s.([' S_d' int2str(i)]); %
See "dynamic field names"

Please note that I am a beginner.
Thanks in advance,
Florent

In this line:

s = load([S_d' int2str(i) '.txt']);

did you mean:

s = load(['S_d' int2str(i) '.txt']); % note the extra apostrophe before S_d
