log10

log10 returns the base-10 logarithm of its parameter.

r = log10(m)

Return Value

r is the base-10 logarithm of m.

Parameters

m

m is a real or complex matrix.

Example

The following functions calculates the number of decimal places for a given axis increment using the log10 function:

def GetNeededDecimalPlaces(rsDelta)
{
    if (abs(rsDelta) == 0.0) {
        l10 = 1.0;
    } else {
        l10 = log10(abs(rsDelta));
    }

    if (l10 < 0.0) {
        return int(-floor(l10));
    } else {
        return 0;
    }
}
