Linear Interpolation Using MathCAD 1

[judeotuks]

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

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

Hi excognito

Thanks, that was very helpful.

Meanwhile, I have a vector Qf with some values greater than 1 .

How do i write a command to make Qf maximum as 1.

Please see attached

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.

Hi IRstuff

I have tried the "If" Statement but it get a scalar instead of a vector.

Please see the worksheet (page 7) for more clarity
