dynamic matrix with changing variable name in for loop

22 views (last 30 days)
I want to rename each matrix in a loop. There are two variable 'mat" and "ser". I tried the code below. Did not work. Any recommendations? Thank you
E_list=[ 1.2E-4, 1.2E-3, 1.2E-2, 1.2E-1, 1, 10, 100]
for i=1:size(E_list)-1
..... Some calculations to get objective and popt below
([mat,'_parameters_',num2str(ser)])(i,3:6))=popt % Parameters

Forcing numbers (e.g. "ser") into variable names is a sign that you are doing something wrong.
Forcing meta-data (e.g. "Glass") into variable names is a sign that you are doing something wrong.
Meta-data is data, and data belongs in variables, not in variable names.
MATLAB is designed to work simply and efficiently using indexing. You should use indexing.

Do not dynamically name variables. This is bad programming practice and will leave you with hard-to-use variables downstream in your code. Instead, use cell arrays or struct arrays etc. See this link for more discussion:
