stft = (Of_rightHandAccx_filtered,60,'Window',win,'OverlapLength',98,'FFTLength',2048);

As per the error message: check for mismatched delimiters.

stft(Of_rightHandAccx_filtered,60,'Window',win,'OverlapLength',98,'FFTLength',2048);

would work if other variables like: Of_rightHandAccx_filtered and win are deefined correctly.

For further understanding stft() function in MATLAB, go through the documentation I have attached here.

Thanks

On the right hand side of your equal sign you forgot to put the name of the function you were calling, you just list the arguments in parentheses.

Looks like you are using a function related to estimating power spectrums but I'm not sure what function you intended to call

Hi, I get the same error. Can you help please?

global a b t E nu
GP1=(-a/sqrt(3),-b/sqrt(3));
GP2=(a/sqrt(3),-b/sqrt(3));
GP3=(a/sqrt(3),b/sqrt(3));
GP4=(-a/sqrt(3),b/sqrt(3));
