Unfortunately, this function doesn't show... I tried removing the local OCTemp folder and restarting but to no avail. Who can tell me where I can find this function?
First : The menu only appears when you have a matrix as the active window.
Second : You can access the X-Function via the Script Window as follows... // BEGIN SCRIPT integ2 -d // END SCRIPT which opens the dialog. You can click OK if a matrix is active or use the data hunt button or Matrix Browser in the fly out to select the matrix.
Third : You mentioned you want the sum of a matrix. The above calculates the integrated area which is different than a raw sum of the values of a matrix. The integral takes into account the X and Y scale values as well as the z values and the sign of the z values. If you really just want to sum the z values in the matrix, use this: // BEGIN SCRIPT range ram = [MBook1]MSheet1!1; total(ram)=; // END SCRIPT
