MATLAB: How to store iterated loop sine function in matrix

arrayfor looploop arrayMATLABstored iteration values

I apologize because similar questions have been asked in the past, but I am very much a newbie to Matlab.
I am trying to store iterated results from an AM radio function in a for loop: 
M=0.5;
A=0.5;
Fm=1;
Fc=100;
for x=0:0.0001:1
    y=(1+M*sin(2*pi*Fm*x))*(A*sin(2*pi*Fc*x));
    disp(y)
end
These results will need to be stored in a matrix format so that I can then plot the data as a histogram. Unfortunately, I am struggling to find a way to keep all values for y except the last result. Other suggestions for related topics (such as m(x:)=[x,y]) do not seem to work for me.
Thanks in advance for your help,
Sarah

If you must use a loop, you need to index into it: 
M=0.5;
A=0.5;
Fm=1;
Fc=100;
x=0:0.0001:1;                                                   % Create Vector
for k1 = 1:numel(x)
    y(k1) = (1+M*sin(2*pi*Fm*x(k1)))*(A*sin(2*pi*Fc*x(k1)));
     disp(y)
end
However if you wnat one vector for ‘y’ it is better to use vectorized code: 
x=0:0.0001:1;
y=(1+M*sin(2*pi*Fm*x)).*(A*sin(2*pi*Fc*x));
Both produce the same result. The second is much faster and more efficient.
