log(b,x) works in MuPad but not in the command line

Hello folks! i am new at this.. mmm why this version of the log function,log (b,x), works only in MuPad window but not if i enter it in MATLAB command window. this error msg appears when i entered in the command line "Error using log Too many input arguments." any help

Then use

log(x)/log(b)

I know this is an equivalent expression>>> but i thought there might be something simpler... but thanks :)

You can create your own function

logb=@(b,x) log(x)/log(b)

then call it

b=10
x=5
logb(b,x)

MuPAD is really a separate programming language. Not all parts of it have been interfaced directly to MATLAB.
