Unable to perform assignment because the size of the left side is 1-by-201 and the size of the right side is 200-by-1

1 次查看(过去 30 天)
Hello, I would like to change my prePeak and posPeak value from 0.0005 to 1/fs(which is the sampling frequency 24414)*100. However when I change the prePeak and posPeak value to 1/fs*100, I get the error message "Unable to perform assignment because the size of the left side is 1-by-201 and the size of the right side is 200-by-1". Any suggestion on how I should modify the code?
Thanks!

If you are certain that you will have a constant number of entries (201) for each time range, then it usually makes more sense to reshape() than to do the kind of looping you are doing.
I notice you are using a closed interval. If there happened to be any point that is exactly at one of the interval boundaries, then that point would be included in two different intervals, which would throw off the assumption of constant number of points per interval.

Replace:
ts = -prePeak:1/fs:posPeak;
by
ts = linspace(prePeak, postPeak, 201);
But as far as I can see, you use ts only to measure its length. Then simply omit the definition and replace "length(ts)" by "201".
I'm not sure where the "201" is coming from, but I cannot know, why neural.spikes(S) has 201 elements.

@feng du: It's impossible to say how to fix this problem without seeing your code and data. I suggest you open a new question and share your code and data there.
