Adding a scalar to every other Column in a Matrix

Adding a scalar to every other Column in a Matrix

Using: MathCAD Prime 9.0

Hello,

I am trying to add a scalar value to every other column in a large matrix (each element in an even column). I included a screenshot below of a small scale example of the input matrix M, scalar value to add, and the desired output. I thought this might be able to be accomplished using a for loop of some kind looping through the elements and only adding the scalar to the even columns, but I wasn't able to figure out how to do this.

The real application is I have a large matrix of time and current values with every other column being the time columns, and want to add a scalar value to shift the time values.

 Any help would be greatly appreciated!

I would suggest using a small user-written utility function (which also should be ORIGIN-aware for maximal portability):
