One way:

L = @(a) [9*(a>90) + 90*(a<90) + 0*(a==90)];
L_test = L([45 135 90]);

You should probably review the basics of MATLAB. E.g.,

As for your particular request, simply taking your words and forming them into pseudo-code:

When a>90°
   the value of L is 9；
when a<90°，
   the value of L is 90

Turning each line into MATLAB syntax yields:

if( a > 90 )
    L = 9;
elseif( a < 90 )
    L = 90;
end

Then note that you have not covered the case where a == 90 exactly.
