what is MSE in newrb

I have a code for new rb

A=rand(64,2);

Tc=[ones(64,1) 2*ones(64,1)];

D=newrb(A,Tc);

E=A(:,2);

Y=sim(D,E)

NEWRB, neurons = 0, MSE = 0.25

i get output as 2(64x1),but what that MSE means,please tell

and i have been asked to take 40 datas(40x2) for training nd rest for testing,if i perform i get error

Error using ==> network.sim at 178 Inputs are incorrectly sized for network. Matrix must have 64 rows.

so please can anyone tell what command must be used

MSE is mean squared error.

OK BUT in my output i get ass value as 2,but why i get MSE as 0.25

MEAN squared error

Answer 1

use, for any network m=mse(name_of_network,output_of _network,target_of_network)
