Hi all, how can i solve this error:
t=Tp';
dt =t(2)-t(1);
vdrift = filter(d,drift)/dt;
delay=mean(grpdelay(d))
tt = t(1:end-delay);
vd = vdrift;
vd(1:delay) = [];
tt(1:delay) = [];
vd(1:delay) = [];
[pkp,lcp] = findpeaks(drift);
zcp = zeros(size(lcp));
[pkm,lcm] = findpeaks(-drift);
zcm = zeros(size(lcm));
figure,plot(t,drift,t([lcp lcm]),[pkp -pkm],'-',"LineWidth",2)
Error

Multiple problems.
[lcp lcm] % this expression gives the error you are reporting
[pkp -pkm] % same error
Error using horzcat
Dimensions of arrays being concatenated are not consistent.
And since the arrays are wrong, it is not clear what your intent is. Did you want to stack lcp over lcm, like this:
a = [lcp; lcm];
length(a)
ans =
1859
Moving on, the following at least corrects the error message:
plot(t,drift, t([lcp; lcm]),[pkp; -pkm], '-', "LineWidth", 2);

Hi Miguel,
When you type [var1 var2], you are concatenating horizontally, since your variables have different number of rows, you'll get an error.
This seems troublesome, I don't really understand what are you trying to do here, can you explain?
t([lcp lcm]),[pkp -pkm]

Take a look at findpeaks and max in documentation. First one requires Signal Processing Toolbox.
