MATLAB: How to extract data to a certain number

data extraction

Say for example I have an array, x=(1:0.25:10) and I want only the data points up to a certain number. How would I do this?

Lest say I wanted all values up until I get the number 2.

(1,1.25,1.5, 1.75, 2) How could I extract just these numbers?

x(x<=2)

Try this

A = [ 1.002 2.003 3.004 4.005 339.006 341.007 342.008 343.009 1.002 2.003 3.004 4.005];% your array 
A(A>300) = 360-A(A>300) % you want

x = linspace(0, pi, 10);
