i have a signal with data length (1x200). how to convert that into square matrix? will the shape of the signal change after converting into matrix? without changing the signal shape is it possible to convert it to matrix.

You can convert an array of m*n elements into a matrix using reshape... read about reshape......
Eg:
data = rand(100,1) ;
matrix = reshape(k,[10,10])
Note that to reshape an array into matrix, the number of elements must be equal.

200 is not a square, so you cannot arrange the values in a square matrix. The smallest square that is at least 200 would be 225, which is 15*15
If you have the Signal processing toolbox, look at using buffer()
