Rik on 21 Nov Some body please guide me how to find the natural log of a value in Matlab. Etiquetas ln.

Help Center Help Center. Array X must contain only nonnegative real numbers. The size of Y is the same as the size of X. If X is a table or timetable, then Y is a table or timetable. Input, specified as a scalar, vector, matrix, multidimensional array, table, or timetable.

Input array, specified as a scalar, vector, matrix, multidimensional array, table, or timetable. Logarithm values, returned as a scalar, vector, matrix, multidimensional array, table, or timetable. For complex and negative real values of X , Y is complex. The data type of Y is the same as that of X. This function fully supports tall arrays. For more information, see Tall Arrays. When the input value x is real, but the output should be complex, simulation ends with an error.

Unless the input exp 1 is treated as a special case, that seems like a very clever implementation of log. Ra: Compute natural logarithm of symbolic matrix variables The log function accepts an input argument of type symmatrix. Any help would be great, Thank you. You could write a function for it as:. Toggle Main Navigation. Buscar MathWorks. Do you want to open this example with your edits? So the comment is correct, it is just needlessly convoluted. I never said "that log is having to treat binary double precision exp 1 specially to get exactly double precision 1" and I'm not saying it now. It seems like you're suggesting that numerical log just does what it does, and its algorithm is such that the floating point representation of the result of applying that alogrithm to exp 1 is exactly 1. In matlab, the general log without radix is equivalent to natural logarithm e. You don't have to define the base. For more information, see Direct Calculations on Tables and Timetables. All variables must have data types that support the calculation. Walter Roberson el 28 de Mayo de

Languages that use log for natural log and do not support ln for natural log. If the output of the function running on the GPU can be complex, then you must explicitly specify its input arguments as complex. To avoid this confusion, perhaps Matlab should not have a function called log at all, forcing you to specify the base.
