log10(x), x REAL or a structure with REAL components

Keywords: transformations
log10(x) returns the common logarithm (base 10 log) of the elements of
x, when x is a REAL scalar, vector, matrix or array.  The result has the
same shape as x.

If any element of x is MISSING, so is the corresponding element of
log10(x).  If any element of x <= 0, the corresonding element of
log10(x) is MISSING.  In both cases a warning message is printed.

When x is a structure, all of whose non-structure components are REAL,
log10(x) is a structure of the same shape and with the same component
names as x, with each non-structure component transformed by log10().

See topic 'transformations' for more information on log10().
