Hi all,

I've got a microcontroller reading values from two sensors and sending
serially to MATLAB. It sends the first value, new line (ASCII 13, or
whatever I decide), then the second value, new line, etc.

If there's only one value i have no problem assigning that to a
variable. But my problem is in splitting the string at the new line.
Is it possible?

Thanks,
Ash

Hi,
You can just make a small .m file to read in the input string and returns
back the values by searching the string for the "new line character" you
decided to using one of the string search functions such as strfind:

example:
S = 'Find the starting indices of the pattern string';
strfind(S, 'in')
ans =
     2    15    19    45

Hope that helps,
Best regards,

Hi Ashraf
Did you mean? E.g.

y1=y(:,1); % channel 1 column of data
y2=y(:,2); % channel 2 column of data
ys=y2(10:end); % splitting data points from 10 to the end for vector y2
