Matrix Syntax ------------------ A = [1,2,3,4] creates a new matrix A(1) selects the first element of a matrix, **zero-indexed** B = [ [1,2,3], [4,5,6], [7,8,9] ] creates a one dimensional matrix :: B = [ [1,2,3], [4,5,6], [7,8,9] ] creates a two dimensional matrix Matrix Operations ------------------ ``inv`` inverts a square matrix Meta-Commands ------------------ Placing a semicolon at the end of a line prevents the output from being printed to screen. ``whos`` Displays variables and their size ``format long``/``format short`` Selects either 4 or 14 decimal place display
