CLsqFit:GetErrChan

CLsqFit:GetErrChan

The GetErrChan method returns the channel at which a fit error occurred. If Fit returns false, use this method along with GetErrMsg to obtain error information.

Syntax

nChannel = CLsqFit:GetErrChan()

nChannel is a number indicating the channel where the error occurred.

Example

The following script configures the fit but forgets to add any data points. After the fit fails, the script prints an error message and exits.

L = CLsqFit:new()	-- create a CLsqFit object
L:SetNumCoefs( 2 )	-- specify the number of coefficients
	-- forget to add data points
bSuccess = L:Fit()	-- do the fit
if not bSuccess then	-- test whether the fit succeeded
n = L:GetErrChan()	-- get the error channel
s = L:GetErrMsg(n)	-- get the error message
Exit( Sprintf("Error [%d] %s\n", n, s ) )	-- exit the script and list the error message
end	-- end of test block
