How do I type the below pseudocode in MATLAB?

program First

integer i, imin, n <-- 30

real error, y, x <-- 0.5, h <--1, emin <--1

for i = 1 to n

h <-- 0.25h

y <-- [sin(x+h) - y]/h

error <-- |cos(x) -y|;

output i, h, y, error

if error < emin then

emin <-- error, imin <-- 1

end if

end for

output imin, emin

end program First
