A Problem with log10. Learn more about log10, matrix array MATLAB

Tường Nguyễn Minh I think, yes, d0 in the log10(d/d0) usually refers to the breakpoint distance. Depending on what path loss model is being used, the calculation of d0 may vary.

For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf,Inf). For complex and negative real values of X, the log10 function returns complex values. MATLAB: Faster “log10” command log MATLAB speed Hi all, Is anyone know how to use the "log10" more wisely? currently, I convert from dB to decimal using log10 but it seems to slow down the execution process. If MATLAB is slow every time you enter a command to run during a session, then it could be that MATLAB is having trouble finding your license, or is otherwise slow during your license check.

It is particularly log, log10, cos, tan, asin, . The lookfor command is quite useful; however it may be very slow in the Mathe- mati that MATLAB is a scripting language, it runs slower than compiled languages. To use The figure describes how time consumption (in log 10 base) is. I'm fairly new to python (coming from matlab) and this same code runs 5x slower in python than matlab (and Julia), which got my attention.

Certain things must be learned the hard way. I learned this one bleary eyed evening as an undergraduate. Well into the night working on a MATLAB homework assignment that would “take ten minutes, fifteen if you type slow.” (yes, Dr. P, 13 years later I still remember that one! -smile-) It is really easy to mistake a .5 for a 5.

Common (base 10) logarithm mod.

y = a+b*i,有log (y) = log (abs (y))+i*atan2 (b,a) 1、log 10函数：求以 10 为底的对数 2、用法说明 y = log 10 (x) 函数对数组x的元素逐个进行以 10 为底的对数运算。. y = a+b*i，有log 10 (y) = log 10 (abs (y))+i*atan2 (b,a) 3、举例说明 >> x = 20 x = 20 >> y = log 10 (x) y = First, please never name your variables the same as built-in MATLAB functions, such as log10. MATLAB will take the most recent definition (as it did in your code) and treat it as a variable rather than a function. I renamed your ‘log10’ array ‘Log_10’ to be sure that you do not ‘overshadow’ the log10 function. Y = log10(X) devuelve el logaritmo común de cada elemento de la matriz X. La función acepta entradas tanto reales como complejas. Para valores reales de X en el intervalo (0, Inf), log10 devuelve valores reales en el intervalo (-Inf,Inf).

LOG vs LOG10 plot . Learn more about loglog, log10, log 5*log10 (A) So if A = 1000, the 5*log10 (A) is 15. You get 15 - the sum of the two matrices B and M2. B = ones (5,5); M2 = 2*ones (5,5); A = 1000; M = 5*log10 (A) - B + M2; So for the above you get 15- a matrix of ones, that gives you a matrix of 14's. And then you add a matrix of 2's so you get a matrix of 16's.

I uninstalled and reinstalled MATLAB which was of no use. Compute the log base 10 of symbolic input. The result is in terms of log.
