Conformable matrix

From Wikipedia, the free encyclopedia

In mathematics, a matrix is conformable if its dimensions are suitable for defining some operation (e.g. addition, multiplication, etc.).

[edit] Examples

  • In order to be conformable to addition, matrices need to have the same dimensions. Thus A, B and C all must have dimensions m × n in the equation
A + B = C
for some fixed m and n.
AB = C.
If A has dimensions m × n, then B has to have dimensions n × p for some p, so that C will have dimensions m × p.
