how to generate a toeplitz matrix with dimension (100 x 150) using matlab.

If i give toeplitz(a,b) and i defined a=[1 0 1 0]:, b=[1 0 1 1] with the help of repmat i can access the matrix in the dimension of 100 X 150 but it doesnt satisfy the Incoherence and RIP .so i want to generate a toeplitz measurement matrix, just by assigning the number like toeplitz(100,150).

If any one know, pls suggest me too...

Thanks in advance.

It is doubtful that anyone will understand what you mean by Incoherence and RIP, though I'm guessing it is from Compressed Sensing. Show what you mean by using repmat to go from a 4x4 Toeplitz matrix to something 100x150 and what it doesn't satisfy.

hi Matt J, Thanks for your reply. i want to generate 1's and 0's with the help of toeplitz matrix. am using it for compressive sensing only..thats why i told, it should satisfy both RIP (Restricted Isometry Property) and Coherence property.

Thanks in advance.

Yes, but I don't think anyone here knows what that means, nor what you did with repmat to try to satisfy it. That's why I said I think you'll have to explain it differently.

This generates a 100x150 Toeplitz matrix, T.

 a=1:100; b=1:150; T=toeplitz(a,b);

Why can't this do what you need for an appropriate choice of a,b?
