cat - concatenation of input variables
This function concatenate the input vectors or matrixes. The number of input variables should be two or three. Row vector and column vector are both allowed. However, the result is row vector.
This function is useful when assembling some coefficients to a predefined storing format which is used in multiple stride decomposition. Hence one could make some modifications on individual coefficients independently and assemble them back to give a reconstruction.
