generate a 5*8 matrix of random numbers and next write a programme using "for" and "if" loops to replace numbers less than 0.5 with "0" and numbers 0.5 or above with 1.

There are no "if loops", to be correct.

So the way without the for and if loops is:
X=rand(5,8)
X(X<(0.5))=0;
X(X>(0.5))=1;
if you really want to use loops:
X=rand(5,8)
for i=1:5
for m=1:8
if X(i,m)<=0.5
X(i,m)=0;
else X(i,m)=1;
end
end
end

Hello H ZETT M,
First of all thanks for your quick response.
Once i run the code, it shows only the random matrix. Did you miss something???
I await your prompt action.
Have a nice day:) Thank you!

@Ahamed KMR: You are waiting H ZETT M's prompt action?! This sounds rather impolite considering the fact, that he or she has almost solved your homework. The remaining work to do is really tiny, so please do show any own effort.
Posting homework solutions is a drawback for the reputation of the forum. In my university posting solutions programmed by others without mentioning this clearly was treated as cheating and one can loose the status as student.
