Description

DVcell_data_math performs arbitrary math operations on up to four cell-based data sets. You can use any operation or expression that can be specified in the V language to operate on the data. The expression you enter may use #1, #2, #3, and
#4 to stand for the four input fields.

Input Ports

string+IPort2 operation

The elementwise math expression to perform on the input fields' cell data set(s). Use #1 through #4 to refer to the input fields.

Mesh+Cell_Data+IPort2+nonotify &in1

One of the input fields.

Mesh+Cell_Data+IPort2+nonotify &in2

One of the input fields.

Mesh+Cell_Data+IPort2+nonotify &in3

One of the input fields.

Mesh+Cell_Data+IPort2+nonotify &in4

One of the input fields.

int+IPort2 data_type

The desired type of the output data set, as follows:

Output Ports

Mesh+Cell_Data+OPort2+nonotify &out

The output field containing the resulting cell data set.
