Hi I am simulating Gaussian noise generator block in simulink.But I am receiving following errors.Can any one please help me how to fix this.

1. Error in 'test1/Gaussian Noise Generator': Initialization commands cannot be evaluated. here test1 is name of simulink model. 2.Undefined function or method 'commblkgaussiansrc2' for input arguments of type 'cell'.

Thank you for your answers.

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 Jiang thank you for your response.

But I am using only gaussian noise generator block and scope in my simulink model.

noise block parameter values ar as follows

Mean:0

variance:1

initial seed: 41

sample time: 1

output data type: double

Still I am getting similar problem.

When I double click gaussain noise generator block in simulink model it shows following message with in stars.

****************************************************************

error due to multiple causes

--> Error evaluating 'Mask Callback' callback of gaussian noise generator block (mask) 'gaussian noise generator'.Undefined function or method

'commblkgaussiansrc2' for input arguments of type 'char'.

Except this noise block all other blocks are working fine in simulink.

Can you please suggest how to fix this.

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.
