hypermat

initializes an N dimensional matrix

Calling Sequence

M = hypermat(dims [,v])

Arguments

dims

a vector of hypermatrix dimensions.

v

a vector of hypermatrix entries (default value zeros(prod(dims),1)).

Description

The hypermat function initializes a hypermatrix whose dimensions are given in the vector dims and entries are given in optional argument v.

M data structure contains the vector of matrix dimensions M('dims') and the vector of entries M('entries') such as the leftmost subcripts vary first [M(1,1,..);..;M(n1,1,..);...;M(1,n2,..);..;M(n1,n2,..);...]

If you build your own hypermat, you must be careful. The M('dims') entry must be a row vector whereas the M('entries') must be a column vector.

Examples

M = hypermat([2 3 2 2],1:24)
disp(size(M('dims')))
disp(size(M('entries')))
 
M_own            = mlist(['hm','dims','entries']);
M_own('dims')    = [2 3 2 2];
M_own('entries') = [1:24]';
disp(size(M_own('dims')))
disp(size(M_own('entries')))
