cell

Create 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'
