| 75 Additionally, @code{cellfun} accepts an arbitrary function @var{func}\n\ | |
| 76 in the form of an inline function, function handle, or the name of a\n\ | |
| 5988 | 77 function (in a character string). In the case of a character string\n\ |
| 78 argument, the function must accept a single argument named @var{x}, and\n\ | |
| 79 it must return a string value. The function can take one or more arguments,\n\ | |
| 80 with the inputs args given by @var{c}, @var{d}, etc. Equally the function\n\ | |
| 81 can return one or more output arguments. For example\n\ | |

95 return value. If 'UniformOutput' is false, the outputs are concatenated in\n\ |
| 5988 | 96 a cell array. For example\n\ |
| 97 \n\ | |
| 98 @example\n\ | |
| 99 @group\n\ | |
| 6623 | 100 cellfun (\"tolower(x)\", @{\"Foo\", \"Bar\", \"FooBar\"@},\n\ |

| 5988 | 105 \n\ |
| 106 Given the parameter 'ErrorHandler', then @var{errfunc} defines a function to\n\ | |
| 107 call in case @var{func} generates an error. The form of the function is\n\ | |
| 108 \n\ | |
| 109 @example\n\ | |
| 110 function [@dots{}] = errfunc (@var{s}, @dots{})\n\ | |
| 111 @end example\n\ | |
| 112 \n\ | |
| 113 where there is an additional input argument to @var{errfunc} relative to\n\ | |
| 114 @var{func}, given by @var{s}. This is a structure with the elements\n\ | |
| 115 'identifier', 'message' and 'index', giving respectively the error\n\ | |
| 116 identifier, the error message, and the index into the input arguments\n\ | |
| 117 of the element that caused the error. For example\n\ | |
| 118 \n\ | |
| 119 @example\n\ | |
| 120 @group\n\ | |
| 121 function y = foo (s, x), y = NaN; endfunction\n\ | |
