#Igor pro command line code#

Your execute operation then performs the requested operation. Each time your external operation is invoked, Igor calls your 'execute' operation (called ExecuteXOP1 in this case), passing to it a structure containing the parameters specified by the caller. When your external operation is first invoked, you register it with Igor (by calling the RegisterXOP1 in this case).

#Igor pro command line code#

You fill in the starter code to perform the desired operation and then compile it in your development system. Igor takes this template and generates starter C code. waveH is the mnemonic name for the parameter and is used as a structure field name. This says that the operation name is XOP1 and that it takes one parameter of type wave. In creating an external operation, you start by creating a plain-text template that tells Igor the syntax of your operation. XOP1 testWave // Add one to the test wave. For example, from the Igor command line, the user could execute the following commands:ĭisplay testWave // Display it in a graph In the case of XOP1, it is called only when the user invokes the XOP1 operation from Igor's command line or from a procedure (user-defined function or macro). Usually communication between Igor and the XOP is initiated in response to a user action.

XOP1 illustrates the structure of an XOP. It merely adds one to each element of an Igor wave.
