Hi, so I'm trying to get the n values to multiply each values in the P matrix in order to get the compound interest values, but I'm getting this error, how can I fix this?

Use the code box!
n=[1,3,16];
P=[300 400 500 700 1000]';%transpose
t=4;
y=P.*(1+t/100).^n-P;

Not true.
y =
12.0000 37.4592 261.8944
16.0000 49.9456 349.1925
20.0000 62.4320 436.4906
28.0000 87.4048 611.0869
40.0000 124.8640 872.9812

Oh never mind I see what you mean. I got it to work.
For some reason I though this was needed.
Year_1=y(1);
Year_3=y(2);
Year_16=y(3);
T=table(Year_1 , Year_3, Year_16);
