Hello everybody,

I am working on my own project right now and needing some help now.

What do I want to do?

Matlab should calculate the average out of values for a specific time period.

time (sec) value

0 2

1 3

2 4

3 6

4 7

5 8

6 2

If time is >0 and smaller or equal to 3 sec Matlab should calculate the arithmetic average of the values.

So basically something like this:

IF 0>=time>=3

Do arithmetic average of value

So the result should be (2+3+4+6 )/4 =3,75.

It is my first project with MatLab and I am usually working with other programms.

Thanks for your help.

Your sincerely,

Max

https://in.mathworks.com/company/newsletters/articles/matrix-indexing-in-matlab.html - read the topic logical indexing once you understand that use mean() after that process.

I also suggest you to do MATLAB on-ramp course.

I have one more question...

What should I do if the amout of values are NOT the same?

time1= 1 2 3 END

time 2 = 1 2 3 4 5 END

values1= 4 5 6 END

values2 1 2 4 5 6 END

Should I still put them into one matrix?

在 MATLAB Online 中打开

time=cell(2,1);
time{1} =[ 1 2 3 ]
time{2} =[ 1 2 3 4 5 ]
