MATLAB: How to use “ln” function on each elemnets of the matrix

matlab function

I would like to use ln (natural logarithm) function on each of the matrix element, how can I do that?

with out using loop

Here yourmatrix - double array.

log(yourmatrix)

In MATLAB (and a number of other programming languages), the natural logarithm function is log, not ‘ln’.

a=['how are you?'];
out = ['hello, ',a]
