xlswrite works much faster as Tim pointed. Only thing is I could not make it produce comma delimited cvs. I passed the 65536 row limit with Excel 2010. I found in some places they use xlFormat = 6 instead of 24 but both of them produces tab delimited csv.
For up to 65536 rows and 256 columns (or I assume more in Excel 2007 though I haven't tested), you can write to a csv file super-quick using a modified version of xlswrite. Simply add the enumeration xlFormat = 24 for when ext is csv in the switch-case around line 230 and you simply need to give xlswrite a filename that ends in csv.

This function is great. However, it seems that using "eval" on line 28 is unnecessary. By changing:
var = eval(['cellArray{z,s}']);
to:
var = cellArray{z,s};
you get a significant increase in preformance. 16.5 seconds -> .45 seconds in the example I tested for a large cell.
