I have a data which include point numbers, y_error and x_error belongs to point numbers (mx3 matrix) point numbers are string other values are double. I wanna check whether errors are exceeding particular number and I wanna show which point.

for example;

point numbers=[a;b;c;...]

errors_y=[0.4;0.52;0.25;...]

errors_x=[0.4;0.33;0.51;...]

I wanna check and see which points errors exceeding 0.5, what kind of loop I have to write?

Use find function. In the example below, b contains the positions of elements greater than 0.5 within array a.

a=[.1 .3 .5 .6 .7];
b = find(a>0.5)

b =

       4     5
