just make the matrices upper triangular by making the values below the digonal zero,and then find how many minors can be calcuted.......
No, it is not.
how to multiply two sparse matrices
The product of a p x q and a r x s matrix is defined only if q = r and, if so, it is a p x s matrix.
A product is a operation involving two or more inputs (numbers, matrices, etc). A "number that is half of 12" comprises only a single number and so there cannot be any product.

how to multiply two sparse matrices
The statement that the rank of product of two matrices cannot exceed the rank of either factor is a true statement. The rank of a matrix is the largest number of linearly independent rows or columns. The column rank is equal to the row rank in every matrix.

If the product of two matrices is the identity matrix then one matrix is the inverse or reciprocal of the other matrix. EXAMPLE A =(4 1) A-1 = (0.3 -0.1) then AA-1 = (1 0) .....(2 3)......... (-0.2 0.4)................... (1 1) The dots simply maintain the spacing and serve no other purpose.
Let me correct you: two-dimensional arrays are used in programming to represent matrices. (Matrices are objects of mathematics, arrays are objects of programming.)

The matrix multiplication in c language : c program is used to multiply matrices with two dimensional array. This program multiplies two matrices which will be entered by the user.
No, Triangular prisms have two bases that are triangular but these need not be equilateral.
