Flood::MultilayerPerceptron bug

Note: this bug is known to the author of Flood and he kindly delivered the following patch: download the patch of this bug.

Some simple getters seem to give errors. The error depends on the index of the hidden layer where I request the weights from. See the code below.

}

Screen output depends. Sometimes the program gives an access violation. Sometimes I get:


Flood Error: Matrix Template.

Constructor Matrix(int, int).

Number of rows must be greater than zero.
