How can I create a new vector using the if function?

Hi everyone,

I have the following problem:

I have a vector (V) that range from 0 to 60 and I would like to group these data as following:

* If the value of (V) is between or equal to 0 and 5 , give me 5
* If the value of (V) is between or equal to 6 and 10 , give me 10
...
* If the value of (V) is between or equal to 56 and 60 , give me 60

The vector V contains 60 data, and the new vector should contain also 60 data

Thank you in advance

So you want to round up to the nearest multiple of 5.

Divide by 5, use ceil, then multiply by 5. The only catch is that for 0, this will result in 0. So catch that possibility too using max.

Vhat = 5*ceil(max(1,V/5));

Learn to use tools that apply to entire arrays and vectors in MATLAB.

ceil(V/5) * 5

This misses the 0 case.

Yep
