The function split was introduced in R2016b, so you will not be able to use it with R2013a.

You can probably replace that line with:

rowData = regexp(tempVar,theDelim,'split');

But given that the code was written for R2016b or later, it is quite likely that you will find other incompatibilities.

thanks for your answer. I will download the 2016 version according to your suggestion and try again。

Sorry to bother you, I have re installed matlab2016b, but now I am prompted with this error, which did not appear in the previous version. Do you know what causes this?

[Stephen Cobeldick]

It appears that theData is a cell array and rowData is a string array, thus the allocation throws this error:

C = {1,2,3};
C{3} = "cat";  % assign to cell content is okay
C(2) = {"in"}; % assign cell to cell is okay
C(2) = "hat";  % assign string to cell -> error

The following error occurred converting from string to cell:
Conversion to cell from string is not possible.

I suspect that there is an input type incompatibility, e.g. the code is not written to handle strings, but you are providing strings as input data. To remove that given error, it seems that the RHS must be a cell array (presumably of character vectors).

You should check the documentation of the code that you are using, to see what input types are supported.

Thank you for your timely reply, I will follow your suggestions for the next step.

If there are still problems, I hope to consult you again.
