when i have processed this code with math script i found one errror . how we can elliminate this error.

only i want to proces this dc shift function by labview.

i am forwarding the codes which are

function [Sig]= dcshift(Signal)
Signal=load('C:\MATLAB6p5\work\EEG programs\mat files-good 4 sec epochs\Dayanand_36.mat');
n=length(Signal);
avg=0;
for i=1:n
avg=avg+Signal(i).dayanand00_36_00_39;
end
avg=avg/n;
Sig=Signal(i).dayanand00_36_00_39-avg;
hold on
plot(Sig-avg)
plot(Sig)
%plot(avg)
hold off
axis([300 400 -inf inf])

thanks & regards

Hello rachana,

The "Signal" variable in your function is a structure array. Unfortunately, LabVIEW MathScript does not have support for structures at this time. One solution to work around this error is to restructure your save file. It looks like you are only using one field in the structure: dayanand00_36_00_39. Instead of saving a structure array, you could save an array of these points. Then you can load this array and work with it in LabVIEW MathScript.
