How to assign a different name of a matrix for each iteration?

조회 수: 2(최근 30일)
Hi everyone,
I am trying to, for each iteration (that goes from 1 to 270), assign a different name for the result matrix of the function modalfit from Matlab Signal Processing Toolbox.
The matrix is a 1x10 for each iteration.
For example, I want for j=1 that the matrix is called [fn1] and saved in the workspace...
This is the code:
for j = 1 : size(varargout,2)
[fn]= modalfit(varargout{1,j}, f, fs, 10, 'FreqRange', [0 3000], 'FitMethod' , 'PP');
end
I would be very happy to be helped.
Thanks, Ana

% preallocation
fn = cell(size(varargout,2),1);
for j = 1 : size(varargout,2)
fn{j} = modalfit(varargout{1,j}, f, fs, 10, 'FreqRange', [0 3000], 'FitMethod' , 'PP');
end
and you can get the desired matrix as fn{1}, fn{2}, etc.

You could use assignin for that purpose:
for j = 1 : size(varargout,2)
fn = modalfit(varargout{1,j}, f, fs, 10, 'FreqRange', [0 3000], 'FitMethod' , 'PP');
assignin('base', ['fn' num2str(i)], fn)
end
but what speaks against storing it all in one 270x10 matrix?
fn = zeros(size(varargout,2), 10)
for j = 1 : size(varargout,2)
fn(j, :) = modalfit(varargout{1,j}, f, fs, 10, 'FreqRange', [0 3000], 'FitMethod' , 'PP');
end
