MATLAB Language Initializing Matrices or arrays
Introduction
Matlab has three important functions to create matrices and set their elements to zeroes, ones, or the identity matrix. (The identity matrix has ones on the main diagonal and zeroes elsewhere.)
Syntax
- Z = zeros(sz,datatype,arraytype)
- X = ones(sz,datatype)
- I = eye(sz,datatype)
Parameters
| Parameter | Details |
|---|---|
| sz | n (for an n x n matrix) |
| sz | n, m (for an n x m matrix) |
| sz | m,n,...,k (for an m-by-n-by-...-by-k matrix) |
| datatype | 'double' (default), 'single', 'int8', 'uint8', 'int16', 'uint16', 'int32', 'uint32', 'int64', or 'uint64' |
| arraytype | 'distributed' |
| arraytype | 'codistributed' |
| arraytype | 'gpuArray' |
Remarks
These functions will create a matrix of doubles, by default.
