(OP)
I need help writing the statement below on mathCAD

C1= 0.2 when beta is less than or equal to 0.9
C1= -0.2 when beta is equal to 1.0

linearly interpolating values between b=0.9 and b=1.0

( please refer to the attached for further clarification)

Thanks

### RE: Linear Interpolation Using MathCAD

Many ways to tackle this problem, here's one.

### RE: Linear Interpolation Using MathCAD

Do you want to clip them or scale everything, i.e., normalize? In any case, you can do something like Q.f[i,j := if(Q.f[i,j]<=1 , Q.f[i,j , 1),
where i,j are predefined indexes , or scale to the max value or whatever

In the future, please post a live worksheet, rather than a picture. While it didn't make any difference this time, there may be other occasions where the live sheet would be infinitely more useful.
