Simply speaking, an n by m matrix is a box of numbers with n rows and m columns. Vectors are a special case of a matrix where there is only one row (a row vector) or only one column (a column vector). Numbers are also a special case of a matrix as Octave regards them as 1 by 1 matrices.

a = 1; b = ones (2, 3); numel ( a, b ) will return 6, as this is the number of ways to index with b . Or the index could be the string ":" which represents the colon operator. For example, a = ones (5, 3); numel ( a, 2, ":") will return 3 as the second row has three column entries. Recorded with http://screencast-o-matic.com Se hela listan på malinc.se Return the commutation matrix K(m,n) which is the unique M*N by M*N matrix such that K(m,n) * vec(A) = vec(A') for all m by n matrices A. duplication_matrix Return the duplication matrix Dn which is the unique n^2 by n*(n+1)/2 matrix such that Dn vech (A) = vec (A) for all symmetric n by n matrices A.

For example, “scalar”, “matrix”, etc. The function typeinfo (expr) returns the data type of the expr in string form. As said earlier, Octave works very fast with vectors and matrices.

The marker to use can be changed with the styleargument, that is astring defining a marker in the same manner as the plotcommand. Using sum on a matrix in Octave. When a matrix is given to sum as a parameter, the behaviour can be counter intuitive at first. Although you may expect that the sum function returns a single value that is the total of adding all the elements in the matrix together, this is not the case. To see how the sum function handles matrix as an input, let's first define a 2 by 3 matrix: Introduction to Octave Dr. P.J.G.

Start Using Octave Online Octave ordinarily examines the properties of the matrix A and chooses a solver that best matches the matrix. By passing a structure opts to linsolve you can inform Octave directly about the matrix A. In this case Octave will skip the matrix examination and proceed directly to solving the linear system.
