# consist

## Purpose

Check that arguments are consistent.

## Synopsis

    errstring = consist(net, type, inputs, outputs)
    errstring = consist(net, type, inputs)
    errstring = consist(net, type)

## Description

`errstring = consist(net, type, inputs)` takes a network data structure `net` together with a string `type` containing the correct network type, a matrix `inputs` of input vectors and checks that the data structure is consistent with the other arguments. An empty string is returned if there is no error, otherwise the string contains the relevant error message. If the `type` string is empty, then any type of network is allowed.

`errstring = consist(net, type)` takes a network data structure `net` together with a string `type` containing the correct network type, and checks that the two types match.

`errstring = consist(net, type, inputs, outputs)` also checks that the network has the correct number of outputs, and that the number of patterns in the `inputs` and `outputs` is the same. The fields in `net` that are used are

      type
      nin
      nout

## Example

`mlpfwd`, the function that propagates values forward through an MLP network, has the following check at the head of the file:

    errstring = consist(net, 'mlp', x, t);
    if ~isempty(errstring)
      error(errstring)
    end
