STORING RESULTS OF MULTIPLE EQUATION INTO A CUSTOMIZED ARRAY

If x varies as 0:0.1:1.57

and if you have y = sin (x) and z = cos(x)

and if you want to store values of sin(x) lesser than 0.6 into a (m,1) matrix 'A', followed by a values of cos(x) greater than 0.8 in the same matrix 'A' finally giving you a (n,1) matrix like below,

A = 
0
0.0998
0.1987
0.2955
0.3894
0.4794
0.5646
1.0000
0.9950
0.9801
0.9553
0.9211

I know this is possible, just can't figure out how? can you please help.

Thank you

Try this

x = (0:0.1:1.57).';
y = sin(x);
z = cos(x);

A = [y(y<0.6); z(z>0.8)];

Result

>> A
A =
         0
    0.0998
    0.1987
    0.2955
    0.3894
    0.4794
    0.5646
    1.0000
    0.9950
    0.9801
    0.9553
    0.9211
    0.8776
    0.8253

It is called MATrix LABoratory for a reason ;)

I am glad to be of help.
