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

在 MATLAB Online 中打开

A(A > -0.15 & A < 0.15)

A(abs(A) < 0.15)

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

Martha
