Line 1: AIn [[~~matrix (~~mathematics~~)\|matrix~~]], ina [[matrix (mathematics)\|matrix]] is '''conformable''' if its dimensions are suitable for defining some operation (''e.g.'' addition, multiplication, etc.). ==Examples== * In order to be conformable to addition, matrices need to have the same dimension. Thus ''A'', ''B'' and ''C'' all must have dimension ''m'' × ''n'' in the equation ::<math>A + B = C</math> :for some fixed ''m'' and ''n''. * For [[matrix multiplication]], consider the equation ::<math>AB = C.</math> :If ''A'' has dimension ''m'' × ''n'', then ''B'' has to have dimension ''n'' × ''p'' for some ''p'', so that ''C'' will have dimension ''m'' × ''p''. ==See also==
