Introduction As Scilab is built around matrices we are forced to use them Scilab stores numbers (and characters) in matrices A matrix can be seen as a table, consisting of m rows and n columns (mxn matrices, also denoted ixj matrices) Scalar variables do not exist per se, they are treated as 1x1 matrices The general form of a Scilab matrix (here 3x3 matrix) is A = [11 12 13; 21 22 23; 31 32 33] Row elements can also be separated by commas: A = [11, 12, 13; 21, 22, 23; 31, 32, 33] In both cases semicolons separate rows The next page shows both alternatives for the 3x3 matrix “[The vector] has never been of the slightest use to any creature.” Attributed to Lord Kelvin
