%ZSCOREJO zscore function adapted to ABR data-structure
%   basically the default zscore function of Matlab but adapted to the
%   structure of ABR data

% divide input data into trials
inData = reshape(inData,[],1);

% perform z score normalisation
outData = zscore(inData);

% restore original shape of input data
outData = reshape(outData,pSmpl,[]);
