#!F-adobe-helvetica-medium-r-normal--18* #!N #!N #!Rtall527 Matrices #!N #!N #!N Matrices are 2-dimensional collections of scalars. They are used to represent, among other things, the coefficients of a set of simultaneous equations or a transformation of a vector. #!N #!N Matrices are constructed from a sequence of vectors enclosed by square brackets. Each of the vectors contained in a matrix must have the same length as all of the others. The following are all valid matrices: #!CForestGreen #!N #!N #!F-adobe-courier-bold-r-normal--18* #!N #!N [[1 0 0 0][0 1 0 0][0 0 1 0][0 0 0 1]] // a 4x4 identity matrix #!N #!N [[ 0.707 0.707 0.000] // a 45-degree rotation #!N [-0.707 0.707 0.000] // about the Z axis #!N [ 0.000 0.000 1.000]] #!N #!N [[1 1 1 1][2 2 2 2]] // a 2x4 matrix #!EF #!N #!N #!EC #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Ltall529,dxall529 h Tensors #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
