MATRIXSCALARLOG (a,afactor)

• $a$ is any matrix.
• $afactor$ is any constant value.

Description

• This funcion gives the Log value of the given matrix entries.
• Logarithm is the inverse operation of exponentiation.
• In $MATRIXSCALARLOG(a,afactor)$, $a$ is any matrix and $afactor$ is the base of the log value.
• This function can be used to find the logarithm numbers with a specified base.If we are not assigned any base value then it will assigned the base as "e".
• Otherwise the base values vary as 2 ,3,4,5 10 and so on.
• Here this function will calculate the log value of each entries in the given matrix.
• So all the entries in the matrix are having same base of the log value.
