MATLAB: How to Log10 X and Y

loglog10

I'm trying to log10 x = [ 1 2 3 4] and y = [5 7 9 9]. I got the log10 for x, but for some reason I can't get y. I used y = log10(x). Thank you in advance.
I have x = [ 1 2 3 4 ]
y = [ 5 7 9 9 ]
Im trying to get the log10 for these. How do I do that?

Best Answer

clc
clear all
x=[1 2 3 4]
y=[5 7 9 9]
log10(x)
log10(y)
this code worked well.
Your question is littel bit concusing. It is not clear.
Do you mean that if we apply log10(x) we should get y ??
the valurswhich are stored in y are not the log10(x) values.
observe that y is having two 9's. you cant get the same value for both 3 and 4.
I think this must clear your doubt.if not please specify the question more clearely.
give up thumb if this answer works. Thank you.
