Thread Subject: Problems with export function

Hello,

I want to export the data as xls file. But when I do so, an error has
occured. Here is the command I typed:

[phi,psi,xval] = wavefun('Haar', 8);
xlswrite('sample.xls', xval)

It said that I cannot save the data because the excel does not support
more than 256 rows and 65536 columns.. what should I do?

I am so frustrated because this is the first step of my project.
