Computes the base X logarithm of a specified input value.

(x>0, y>0). If y is 0, the output is - $\infty$. When x and y are both non-complex and x is less than or equal to 0, or y is less than 0, the output is not a number (NaN).

## y

An input to this operation.

This input supports scalar numbers, arrays or clusters of numbers, and arrays of clusters of numbers.

## logx(y)

Logarithm of y to the base x.

When x and y are complex, the following equation defines logx(y):
$\mathrm{log}x\left(y\right)=\frac{\mathrm{ln}\left(y\right)}{\mathrm{ln}\left(x\right)}$
