The log2 function can calculate on all variables within a table or timetable without indexing to access those variables. All variables must have data types that support the calculation.

1 Οκτ 2019 · Use the taylor'd log2 formula; the result will be less than eps() from what it should be. The log2 of the resulting value will be between 0 and 1 (to within eps). Now add to that log2 the integer difference between the actual binary exponent and 0x3ff : the result will be the log2 of the original number.
example. Y = log2(X) computes the base 2 logarithm of the elements of X such that 2 Y = X. example. [F,E] = log2(X) returns arrays F and E such that X = F ⋅ 2 E. The values in F are typically in the range 0.5 <= abs(F) < 1.
Logarithm values, returned as a scalar, vector, matrix, multidimensional array, table, or timetable. For positive real values of X in the interval (0, Inf), Y is in the interval (-Inf, Inf). For complex and negative real values of X, Y is complex. The data type of Y is the same as that of X.
In this lesson, I'll show you how to calculate logarithms of any base in Matlab using some practical examples. Natural logarithm. First, let's consider the natural logarithm. To calculate it, you simply use the "log(x)" function. log(x) For instance, to find the natural logarithm of 9, you would type log(9) and Matlab would return the value of ...
8 Ιαν 2017 · Logm() takes the matrix logarithm, and log2() takes the logarithm base 2 of each element of a matrix. I'm trying to compute the Von Neumann entropy, which involves the base 2 matrix logarithm. How do I do this?
This MATLAB function computes the base 2 logarithm of the elements of X such that 2Y=X.
