MATLAB: How to make array from characters from variables

Create a cell array out of the character array:

c = cellstr(val);

Then, each cell element is a string that can be used:

c{1}

for example, is the first string. (Notice the use of curly brackets there.) You can read more about the use of cell array in the documentation.

MATLAB: KDD data set normalization

1. I do not see where you have confirmed that you have obtained acceptable results from training. Where do you compare training output trainout = sim(net,ivp) with the training target ivt? Is

NMSE = mse(ivt-trainout)/mean(var(ivt',1)) << 1 ?

2. To use the testinput you have to normalize it, use sim, then unnormalize the answer.

Hope this helps.

Thank you for formally accepting my answer
