cell (MATLAB Functions)

Construct cell array

Syntax

c = cell(n)
c = cell(m, n) or c = cell([m n])
c = cell(m, n, p, ...) or c = cell([m n p ...])
c = cell(size(A))
c = cell(javaobj)

Description

c = cell(n) creates an n-by-n cell array of empty matrices. An error message appears if n is not a scalar.

c = cell(m, n) or c = cell([m, n]) creates an m-by-n cell array of empty matrices. Arguments m and n must be scalars.

c = cell(m, n, p,...) or c = cell([m n p ...]) creates an m-by-n-by-p-... cell array of empty matrices. Arguments m, n, p,... must be scalars.

c = cell(size(A)) creates a cell array the same size as A containing all empty matrices.

c = cell(javaobj) converts a Java array or Java object javaobj into a MATLAB cell array. Elements of the resulting cell array will be of the MATLAB type (if any) closest to the Java array elements or Java object.

Examples

This example creates a cell array that is the same size as another array, A.

A = ones(2,2)

A =
     1     1
     1     1

c = cell(size(A))

c = 
     []     []
     []     []

The next example converts an array of java.lang.String objects into a MATLAB cell array.

strArray = java_array('java.lang.String', 3);
strArray(1) = java.lang.String('one');
strArray(2) = java.lang.String('two');
strArray(3) = java.lang.String('three');

cellArray = cell(strArray)
cellArray = 
    'one'
    'two'
    'three'
