Segmentation of a signal

I have row vector of ECG signal have 1 x n order. I want to make 200 segments of that row vector and each segment should contain 300 samples.

For example: First sample should contain values of row vector from 1 to 300, second sample should contain values of row vector 301 to 300 and so on.

How should I start?

Try this

signal200 = reshape(ecgSignal, [], 300);

This is how I want to do it:

1st segment = [300 samples] % 1st sample to 300th sample

2nd segment = [300 samples] % 301 sample to 600th sample

3rd segment = [300 samples] % 601 sample to 900th sample

...

...

...

...

200th segment = [300 samples]

Yep, that's what I did. Each row is one of your "segments". I'm sure you didn't want 200 different, independent variables each with a different name - that would be really dumb.

how can i do signal segmentation by time,for example each segment contain 500 s.

[Image Analyst]

You'd need a cell array because each segment might not have the same number of samples. You can use etime() to find out elapsed times.

Is n a factor of 200 ?

The exact order of row vector is 1*537600
