Hi everyone,
When I uploaded a .mat file to MATLAB, the name of the file appears as "ans" in workspace. Is there any way to correct it? Thanks in advance.

Assign the data to a variable e.g. Data or Data1, Data2 ... if there are more than one file, and access the data using a dot operator as below,
% Assign the data in mat file to a variable
Data1 = load('data_B6_RC1.mat');
Data2 = load('data_B6_RC2.mat');
%...
% access the data from the Data variable ... Data is Struct variable
t = Data1.data_B6_RC1(1,:);
vs = Data1.data_B6_RC1(2,:);
vc = Data1.data_B6_RC1(3,:);

It looks like when the .mat file was saved, the variables weren't saved with their proper names. You could just keep it as it is and do this:
load('data_B6_RC.mat');
t = ans(1,:);
vs = ans(2,:);
vc = ans(3,:);
Or you could resave it as
load('data_B6_RC.mat');
t = ans(1,:);
vs = ans(2,:);
vc = ans(3,:);
save('data_B6_RC_new.mat','t','vs','vc')
and just use the data_B6_RC_new.mat file instead. Or you could overwrite the old file.

I know that the first block of code works, but there is a problem with it: when I upload more than one file, only the last uploaded file appears in workspace because both of them are in workspace with the name "ans". Unfortunately, the second code block didn't work for me.
