How to select element of an array between two values?

Hi,

I have an array of 2800 elements < 2800 x 1 double >, and I want to create a new array only with the values that are greater than -0.15 and less than 0.15. Many Thanks in advance.

Regards, Martha

Answer 1

[Walter Roberson]

A(A > -0.15 & A < 0.15)

or

A(abs(A) < 0.15)

Multi-column analyzing column 1

A(abs(A(:,1)) < 0.15, :)

Thanks Walter, but if I do that is pretty much the same results as the previous answer. I just want to select the columns 1, 2 & 3 for the results given in the first example. Analyzing the elements between -0.15 & 0.15 from column 1 and selecting the rows that match with that condition but from each of the 3 columns.

Thanks. Martha

Thanks Walter,

Both work very well! Do you know also how to do the same but with several columns?, That is, having < 2800 x 3 > but analyzing only values from the first column and return the values from the given rows but all the columns.

Thanks
