input array
a= [1,2,3,4,5,6,7,8,9,10]
the output array is as follows. where 100 is initial value we are calculating for 1. for 2 we are taking output of 1.
b= (1*100)+100 = 200
b = (2*200)+ 200 = 600
b=(3*600)+600 = 2400
like wise i need to calculate for all elements of a.

Ran in:
a= [1,2,3,4,5,6,7,8,9,10];
b = 100; % initial value
for i=1:numel(a)
b= (a(i)*b)+b;
fprintf("i=%2d b=%d\n", i, b)
end
i= 1 b=200 i= 2 b=600 i= 3 b=2400 i= 4 b=12000 i= 5 b=72000 i= 6 b=504000 i= 7 b=4032000 i= 8 b=36288000 i= 9 b=362880000 i=10 b=3991680000
