Neural network transfer function matlab answers matlab. For positive values of integers j and n, wavelet packets are organized in trees. As a result, if a is a scalar, then matlab will return a aa matrix of ones but in scilab you get a 1 just because a scalar is a 11 matrix, so use onesa,a to get the same matrix b. Also include any weighting functions that represent your design requirements. The bivariate function f described by f is evaluated on a 51by51 uniform grid if f is scalarvalued or dvectorvalued with d 2 and the result plotted by surf. When i write matlab code, i have an editor open in one window and i run matlab in another.
