Defining your own using an equality such as. log9(x) = log(x) / log(9). looks to be . See Logarithm to arbitrary base. log(b,x) computes log of x to the base 'b'. Hi, in MATLAB the natural logarithm corresponds to the "log" command. supposing you know how to compute the logarithm with base c of a number: log_b (a). You can pick A to be one of the built in functions, like log or log2 or log E.g.,. log3(9) = log(9) / log(3), or. log3(9) = log10(9) / log10(3), etc. In mathematics, the binary logarithm (log2 n) is the power to which the number 2 must be raised . Because logarithms in different bases differ from each other only by a constant factor, .. In MATLAB, the argument to the log2 function is allowed to be a negative number, and in this case the result will be a complex number. In MuPAD Notebook only, log(b, x) represents the logarithm of x to the base b. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts. Consider this example: %# some random data x = 2.^(); y = rand(size(x)); plot(log2(x), y) %# plot on log2 x-scale set(gca, 'XTickLabel',[]) %# suppress. This article describes the formula syntax and usage of the LOG function in Microsoft Excel. Returns the logarithm of a number to the base you specify.

Bravo, what words..., a remarkable idea
