cellfun

---

Evaluates an function on a cell.

---

Syntax

---

R = cellfun(function_name, ce)

R = cellfun(function_handle, ce)

[R1, ... , Rp] = cellfun(function_handle, ce1, ..., cep)

[R1, ... , Rp] = cellfun(function_handle, ce1, ..., cep, name, value)

Input argument

---

function_handle

a function handle.

ce1, ... , cep

cells with p inputs required for function_handle.

name, value pair

'UniformOutput': true or false, 'ErrorHandler': a error function.

Output argument

---

R1, ... , Rp

Outputs from function

Description

---

cellfun applies function to each cell elements.

Examples

---

greetings = {'Hello', 'Guten Tag', 'Sawadee', 'Bonjour', 'Namaste', ''};
R = cellfun('size', greetings, 1)
R1 = cellfun('size', greetings, 2)

C = {1:10, eye(3,4), eye(5,6)};
f = str2func('size');
[nrows_1, ncols_1] = cellfun(f, C,'UniformOutput', false)
[nrows_2, ncols_2] = cellfun(f, C,'UniformOutput', true)

functions to define for next example:

function r = fun1(x, y)
r = x > y;
end

function result = errorfun(S, varargin)
	disp(nargin())
	disp(S)
	disp(class(varargin))
	disp(size(varargin))
	disp(varargin{1})
	disp(varargin{2})
	result = false;
end

R = str2func('fun1');
H =  str2func('errorfun');
A = {rand(3)};
B = {rand(5)};
AgtA = cellfun(R, A, B, 'ErrorHandler', H, 'UniformOutput', true)
AgtB = cellfun(R, A, B, 'ErrorHandler', H, 'UniformOutput', false)
