dynamic matrix with changing variable name in for loop
显示 更早的评论
Hi,
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]
mat='Glass'
ser=24
for i=1:size(E_list)-1
..... Some calculations to get objective and popt below
......
([mat,'_parameters_',num2str(ser)])(i,1)=E_list(i)
([mat,'_parameters_',num2str(ser)])(i,2))=objective(popt)
([mat,'_parameters_',num2str(ser)])(i,3:6))=popt % Parameters
end

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:
