I am getting the following error
Attempt to execute SCRIPT load as a function:
/Users/naoki/Documents/MATLAB/Add-Ons/TS2004.07/load.m
Error in load (line 17)
mydata{i,k} = load(filename);
And this is my programming:
numFiles = 31;
mydata = cell(31, 7);
for i = 1:numFiles
if i<10
daystr_j = ['0', num2str(i)];
else
daystr_j = num2str(i);
end
for k = 0:7
j = 3*k;
if j<10
daystr_j = ['0', num2str(j)];
else
daystr_j = num2str(j);
end
filename = ['TS2004.07.',daystr_i,'.',daystr_j,'00.txt'];
mydata{i,k} = load(filename);
end
end
I want to load all text datas, TS2004.07.01.0000.txt to TS2004.07.31.2100.txt.
Please give me any advice.

By the way:
daystr_i = sprintf('%02d', i);
saves you from having to test the value or add the leading '0' or do the num2str()

You have written a script called load.m:
/Users/naoki/Documents/MATLAB/Add-Ons/TS2004.07/load.m
That is preventing you from using the MATLAB core load function. This is called ‘overshadowing’, and is to be absolutely avoided.
The solution is to name your function something else, like ‘my_load.m’ or something even more descriptive of its function.

Thank you for answer. I tried, but I still have a same error.

My pleasure.
Type this in your Command Window:
q = which('load', '-all')
When I run that, I get:
q =
'built-in (C:\Program Files\MATLAB\R2016a\toolbox\matlab\general\load)'
'C:\Program Files\MATLAB\R2016a\toolbox\shared\reqmgt\+rmiml\@RmiMlData\RmiMlData.p'
'C:\Program Files\MATLAB\R2016a\toolbox\shared\reqmgt\+rmidata\@RmiData\RmiData.p'
'load is a Java method'
'load is a Java method'
'load is a Java method'
'C:\Program Files\MATLAB\R2016a\toolbox\matlab\winfun\@COM\load.m'
That is all you should get. If you get any other results, that will indicate where the problem is.

It could be a simple bug. You use daystr_i and daystr_j in the filename, but you never set daystr_i. It looks like you set daystr_j twice by accident. Actually it might be a good idea to use variable names which don't look so much alike.
Try that and respond if there's still a problem.
