Hi Bruno,
The error “Inner matrix dimensions must agree” seems to indciate a mismatch in the dimensions of the matrices involved in an operation. Kindly ensure that the input data and the output data are in the correct format. The 'newrb' function expects the input matrix P to have dimensions [R x Q], where R is the number of input features (3 in your case) and Q is the number of samples (1000 in your case). The target matrix T should have dimensions [S x Q], where S is the number of output features (1 in your case) and Q is the number of samples (1000 in your case).
Here’s a sample code to create an RBF network with the inputs and outputs of the specified dimensions:
% Sample input data (3 columns, 1000 rows)
P = rand(3, 1000);
% Sample output data (1 column, 1000 rows)
T = rand(1, 1000);
% Ensure data is in the correct format
if size(P, 1) ~= 3
P = P';
end
if size(T, 1) ~= 1
T = T';
end
net = newrb(P, T);
view(net);
You can refer to the documentation of the function 'newrb' using the following command in MATLAB Command Window:
doc newrb
Hope this helps to resolve the issue.
