Arrays into the fromula node?

[lp19]

Hello,

I am trying to convert my voltages into pressures via the formula node but I am having trouble.

The situation is follows, I have a 1D array of single and I want to convert them using the formula node.

When I enter the equation into the node it tells me that there is an error on line 1 left brace needed.

What is the left brace, this must sound silly but I have no idea what to do.

Please help.

I have other formula nodes working fine but the inputs into them are not arrays they are just single elements (the mean of 1000 points for example).

Thanks

In order to output an array from a formula node, you must declare the array variable.

float32 Y[100]; /* Declare 100-element array output

Inside the formula node, you must work with the arrays just like in C. The left brace is this -> [. It is looking for something like Y[0] = 1 + X[0]; where X is an array input. To make things simple you may consider placing your Formula node as it stands right now into a FOR loop. Your 1D array input will auto-index and your output will become an array as it tunnels out of the loop.
