IF statement inside a FOR loop ERROR

Using h as the FOR loop index variable, begin h at a value of 7,000,000 meters and decreasing h in steps of 0.01 meters, to 4,750,000 meters.

Use the IF statement to detect the first instance when the value of g is within 0.000001 m/s2of 2.53 m/s2. This will be the IF statement’s test. When g and go are that close, then you have found 'h'.

clear; clc; re=6371000; go=9.81; h=700000; x=0; n=1; w=1;

for m =1:n for q=1:w

    g=go*((re/(re+h))^2);

    if (abs(2.53 - g) < 1e-6)

        x=h;

    else
        w=w+1;
        h=h-0.01;
    end
    end

end
