List of linearToLog() Examples

Examples of linearToLog()

edu.cmu.sphinx.util.LogMath.linearToLog()
Converts the value from linear scale to log scale. The log scale numbers are limited by the range of the type float. The linear scale numbers can be any double value. @param linearValue the value to be converted to log scale @return the value in log scale @throws IllegalArgumentException
