What are the parameters that you provided at the parameter dialog window, such as Mean value, Variance, Initial seed, Sample time and Samples per frame. The error message indicates you might have provided a data which is in the type of cell array. Try some very simple example first. If you have data in cell array, such as data={1,2,3}, use data{1} to refer to the first value in the cell array data.

Hi Kaustubha Govind,
I am using matlab with license from my univ.
All other blocks are working except communication blockset.
when I run "which commblkgaussiansrc2". It shows like
>> which commblkgaussiansrc2
C:\Program Files\MATLAB\R2010a\toolbox\commblks\commmasks\commblkgaussiansrc2.m % Has no license available
>>
Can you please mention how can I activate license for this toolbox.
thank you very much for help.

If your university purchased and installed the toolbox, there is really no need to activate it. Once you try to drag and use that Gaussian noise generator block, the license will be checked in (assume it is available if it is a network license). Are you using stand-alone license or network license. The best way is to call TWM tech support. Type ver in Command Window to find out your license number. Give it to TWM and they will tell you what your options are.
