MATRIXSCALARLN (a)

• $a$ is any matrix.

Description

• This function gives the Natural logarithm of the given matrix entries.
• In $MATRIXSCALARLN(a)$,$a$ is any matrix.
• LN is the logarithm in which the base is the irrational number e(e= 2.71828...).
• The ln(x) is the inverse function of the exponential function $e^{ln(x)}=xifx>0$.
• ln(e^x)=x.
• To find the LN value for a matrix ,simply find separately natural logarithm for all the entries for the given matrix.
