kvals = [0.142,0.144,0.156,0.180,0.196,0.205,0.207,0.201,0.177,0.160,0.149,0.142] ;
    upx = -K./sinalpha_angle
    exp_local = exp(upx)

I am trying to take an exponent of a non-integer value (upx) and keep getting the error that "Array indices must be positive integers or logical values". I know that none of these values are an integer but need to take the exponential to the non-integer power.

Any help is appreciated.

It may be that the error is about trying to index a variable called exp with invalid values. Do you have a variable called exp? If so, change it to something else, and if this is a script do clear exp before you run it again.
