How to select/specify function for lagged correlation of a large Matrix

Hello all,

I am attempting to generate a matrix that shows the normalized cross-correlation coefficients for each of 146 variables (arranged in columns) at a lag of 1 time step. The original matrix is [246x146]. Each observation is numeric. I am looking at normxcorr2 which seems relevant on the face, but if so I could use a bit of direction on how to specify a 'template'. Any advice is greatly appreciated.
