I want to convert the following Fortran code to MATLAB. Any help will be appriciated-
NB = 100
F=0.
DO i=1,NB
[some equations]
IF(abs(xm)<wm)
ym=ye+d*sy
IF(abs(ym)<wm) CYCLE
ENDIF
d=LL/sz
xt=xe+d*sx
IF(abs(xt)>wt) CYCLE
yt=ye+d*sy
IF(abs(yt)>wt) CYCLE
F=F+1.
ENDDO

While completely uncommented, this doesn't look very complicated. What have you tried?
It is also possible to compile Fortran to mex, allowing you to call the Fortran function from Matlab.

Here is the equivalent MATLAB code:
NB = 100;
F = 0;
for i=1:NB
% [some equations]
if( abs(xm) < wm )
ym = ye + d*sy;
if( abs(ym) < wm )
continue
end
end
d = LL/sz;
xt = xe + d*sx;
if( abs(xt) > wt )
continue
end
yt = ye + d*sy;
if( abs(yt) > wt )
continue
end
F = F + 1;
end
However, this code looks a bit strange to me. When you look at all the variables that are being tested within the loop, none of them seem to be calculated from anything that is changing within the loop, unless these changes are within the code block labeled [some equations].
