MATLAB: Multiple lines of similar variable names

Question

Hi, I have the following arbitrary MATLAB code. I am just trying to clear outliers out of these matrices but have to repeatedly use the filloutliers command for each individual component. This can become tedious if there are 20+ components to retype over and over, I was wondering if there is a way to perform this task using less lines and less time. Thank you.

A_1 = [1:20, 50]

A_2 = [70:80, 20]

A_3 = [50:60, 2]

B_1 = filloutliers(A_1,'linear');

B_2= filloutliers(A_2,'linear');

B_3 = filloutliers(A_3',linear');

Answer 1

Hi

It is not advisable to change the variable names within the loop due to various reasons mentioned in this link:

But if you still want to work with changing the variables:

%Your input data
A_1 = [1:20, 50]
A_2 = [70:80, 20]
A_3 = [50:60, 2]
for i = 1:1:3
    result = filloutliers(eval(['A_' num2str(i)]),'linear');
    eval(['B_' num2str(i) '= result'])  
end
