I have a program that ran fine in 2017b, but now in 2018a I get a syntax warning:
Warning: This syntax will be removed in a future release. See the documentation for recommended usage. > In movavg (line 77) In leadlag (line 73) In parallel_function>make_general_channel/channel_general (line 917) In remoteParallelFunction (line 46)
How do I find the specific syntax problems? Also, where in the documentation can I read about this and make changes?
The warning is very persistent and outputs to the command window (or to the HTML file if publishing is selected). I've tried to suppress warning, but that doesn't prevent the output. How do I prevent/suppress these warnings when my program executes?

See leadlag.m file of https://www.mathworks.com/matlabcentral/fileexchange/52588-automated-trading-system-development-with-matlab
movavg changed from old functionality:
https://web.archive.org/web/20150312180256/https://www.mathworks.com/help/finance/movavg.html
to the newest one:
https://www.mathworks.com/help/finance/movavg.html
I changed code to:
% [lead,lag] = movavg(P,N,M,'e');
lead = movavg(P,'exponential', N);
lag = movavg(P,'exponential', M);
But unfortunately when comparing old calculated lead and lag to previous ones, results don't match exactly.
