Hi,

I am having problem solving this problem:

Unable to perform assignment because the size of the left side is 2-by-1 and the size of the right
side is 2-by-226.

Here are some parts of the code:

xTrain is a 1x226 Matrix

expectedOutputTrain is a 226x1 Matrix

size of numclasses is 2

inputSize = numel(xTrain);
numHiddenUnits = 5;
numClasses = numel(categories(expectedOutputTrain));
net = trainNetwork(xTrain',expectedOutputTrain,layers,options);
