Trouble with a simple division in my m-file

I have a old m-file that as a company we quickly update to make certain graphics we want. I have data files being brought in, everything is coming in correct.

my equation i have is Rat=(intial/dye)-1

Initial is a one number 97.8

Dye is a matrix of 67 x 1

The Dye numbers range between .15 to .01

BY doing this i am suppose to get a dillution number to go on a semilog plot.

When i run this routine it does not give me any errors but all my numbers generated by this equation are -1.

Any help would be greatly appreciated. thank you in advance

Rat=( initial ./ dye ) - 1

looks more like what you want I think. I assume you want to divide initial by each number in dye independently rather than do a matrix division?
