How can I apply data in function?

wanna show data in function as val = ~ How can I do this....

I'm not sure I understand your question.

Are you asking about how to pass input arguments into a function? If so see this documentation page.

Are you asking how to prompt the user to enter data interactively inside your function? If so look at the input or inputdlg functions, but realize that if you call those functions inside your function then every time your user calls your function they will need to enter the data; you can't call input or inputdlg but "automatically fill in the data".

Are you asking how to ignore input arguments or output arguments in a function definition or a function call respectively? See this documentation page for inputs and this page for outputs.

If those aren't what you were asking, please add some clarification about what exactly you're trying to do.

There are zeros in that function(SumJtCbnMeanAST). and val(:,:,2) means 2nd week data. only 1st, 5th data are on screen. Wanna have 2nd, 3rd, 4th weeks data too.

Can you dynamically create variables with numbered names like x1, x2, x3, etc.? Yes.

Should you do this? The general consensus is no. That Discussions post explains why this is generally discouraged and offers several alternative approaches.

Nowhere in your code do the eval patterns that you're showing generate a dynamic variable name that could end in AST. So it's not clear how you're creating that variable. Fix your code by eliminating the use of eval and show a minimal working example (no more than say a dozen lines of code that we can actually run) that creates that variable and we may be able to offer some guidance.

Debugging that to figure out what's creating / populating that variable is going to be extremely painful since you're dynamically creating / populating those variables with eval. Use one of the techniques on that page to which I linked to eliminate your usage of eval and it may be easier to debug the code.

Thank you for your support, I really appreciate. Have a nice day.
