ztm [Options] A B Vectors Result
This program reads two matrices from A and B, a list of vectors, and calculates the image of the vectors under A⊗B. A and B must be square matrices of dimension m and n, respetively This calculation could be done with the zte and zmu programs, but using ztm avoids the memoryconsuming calculation of A⊗B.
Let m, n be the dimensions of A and B, respectively. For each input vector v∊F^{1×mn}, the program computes the m×n matrix with
Then, v(A⊗B) can be computed by ordinary matrix operations:
Both matrices and one vector must fit into memory at the same time.
