Math Script

[srinivas]

I want program the below equation using math scrip , i am using labview 8.5

Cal =  -10 + (1.3 * ln (x + 0.3)) + (1.2 * ((ln (x + 3.7)) ^ 2)) +(0.03 * ((ln (x + 3.7)) ^ 3)) + (0.05 * ((ln (x + 2.7)) ^ 4))

Where X is control input from user.

Thanks

OK.... so what's your issue? Do you not know how to use MathScript? Are you unsure about the syntax? Are you asking how to set X as a variable? Have you looked at the LabVIEW Help? Have you looked at the examples?

Hi andy,

              I did the same as told by you, i am getting a error "semicolon missing " . i am trying out formula node for the first time

The formula node is a different beast. For MathScript you need to use the MathScript node, located in the Mathematics -> Scripts & Formulas. The MathScript node has a blue border. The formula node has a dark gray border.

Hi ,

          Tried to search for Mathscript under Functions>>Mathematics>> Scripts & Formulas palette but couldnt find only only i can see Xmath Script and Matlab Script . Is there any additional toolkit required ???

Is LabVIEW correctly activated on the computer? Do you have the edition that actually has MathScript? Check by launching the NI License Manager (on Windows it's Start -> All Programs -> National Instruments -> NI License Manager). Then check to see which development version is activated.

Aside: Is there a reason you're not doing this with LabVIEW functions directly?

[srinivas]

just wanted to give a try how it works

[smercurio_fc]

OK, that's fine. I was just curious.

Did you check your activation?
