I was going to ask you the same thing. It's not one of the noise types built in to imnoise().
Perhaps it's the "rice" noise listed in this very comprehensive noise generator: RANDRAW

I have equation but it is multiplicative noise. It can be added anywhere in input signal or image. So it doesn't require same size as input. MATLAB always requires to follow rules of matrix multiplication or addition.

MIMT imnoiseFB() is largely a replacement for IPT imnoise(), though it offers a few new options not offered in the original. One of those added features is an option for Rician noise. If you're curious about the implementation, open up the fle and read the corresponding block. The comments include a web link to references.
From the synopsis:
imnoiseFB(INPICT,'rice',{SIGMA})
Additive Rician noise of the specified scale parameter SIGMA (default 0.05).
