I have performed dwt2 on a image ,and have its coefficient,and sampled it,now i want to quantise the cA,cH coefficients to single image ,please help
the size of cA after sampling ,is 128x128 and cH after sampling is 128x128,now i want to perform quantization on cA,cH and get a single image please help

I don't know what you mean. There is a new imquantize() in the Image Processing Toolbox - I think it started in R2012b. See if that will do what you want.
If you want to do stitching of images instead, just put the in brackets:
horizontallyStitchedImage = [image1, image2]
verticallyStitchedImage = [image1; image2]
Of course the dimension (number of rows or columns) along the stitching seam must be equal.

There is no special syntax for compressive sensing.
There are no Mathworks provided library routines or toolboxes specifically for compressive sensing. You can find some example code in the File Exchange.
