Hi all,
I'm trying to get my code to output a line of text inside a message box, and have it state the value of a variable that it has calculated. The basic idea I want is:
if abs(freq-BPFI)<1.5
msgbox('Event Frequency=<freq> Inner Race Fault Detected','Fault Detected','warn')
end
Where freq is the value of the variable. Could anybody tell me how I can do this? Thanks in advance.
