How to give an initial value to a variable in simulink "matlab function"

The input is "hitin" and the output is "hitout" (on the right-hand side of M function),which is saved as matrix HIT. However, I want to give an initial value to variable,"hitin". i uses "memory" but it has compiling error! If i am right the result of HIT is supposed to be 1 9 9 9 9 .... Hoping somebody can help me.

It looks like the reason for the compile error is that hitout may not be set at all, for example if hitin = -1.

Change the elseif condition to an else condition and the compile error should disappear.

I appreciate,but still have Make error(weird): C:\Users\Kaiser's\Desktop\Passive Walking\bipedal\Kobetest_sfun.mexw64 could not be deleted. Trying to delete again. Two attempts to delete C:\Users\Kaiser's\Desktop\Passive Walking\bipedal\Kobetest_sfun.mexw64 have failed. This file is either not writable or is locked by another process.

Close Matlab, delete Kobetest_sfun.mexw64, start matlab and run again.
