aviread MATLAB function not found

Dear,

In my program Ihave this line:

frm(i)=aviread('test.avi',i);

And I got this error:

Unrecognized function or variable 'aviread'.

Can anyone help me to find this function aviread(filename,index) please!

It is not an inubilt function. Download the function from here:

@KSSV I got an extra error:

Undefined function 'AviReadMex' for input arguments of type 'char'.

@KSSV Not enough input arguments.

Because in my code I have only aviread(filename,index). However, in this function we have aviread(filename,option,option2,option3)
