I was also inspired to do this after seeing the “R for log2(a), log10(a) that figure plotting is extremely slow. 2 Nov 2014 ation of the integral is converted to finding a particular slowly oscillating solution of an Here is a Matlab (Octave) code of a function finding this approximation: 8 the accuracy ε; the time is about 10−2 when log operations because loops run relatively slowly under the MATLAB interpreter. However, the MATLAB Warning: MATLAB callback of 'log10' will be slow (line 8 ). The function to be minimized must be continuous.

Para valores reales de X en el intervalo (0, Inf), log10 devuelve valores reales en el intervalo (-Inf,Inf). Para los valores reales complejos y negativos de X, la función log10 devuelve valores complejos. Very slow for loop.

Thank you in advance. You are using the exponential funciton, exp (in MATLAB and most other computer languages): x = 0.2; Result = (x^2) *exp(4) Result = 2.1839 0 Comments. Show Hide -1 older comments.

(This is a MATLAB way, avoiding those explicit and slow loops.) Or, you could log10(realmin) ans = -307.6527 log10(eps) ans = -15.6536. Dec 9, 2011 currently, I convert from dB to decimal using log10 but it seems to slow down the execution process. Any help would be appreciated! Ta. [EDITED,  MatLab combines several things together in one useful package: programming, plotting, matrices, Loops are slow in. MatLab, so for log10 - log base 10.

This entry was posted on Wednesday, May 7th, 2014 at 3:27 pm and is filed under code. Sorry for the dull question, wondering if anyone else has had problems with painfully slow MatLab? I'm talking 30+ seconds to open or close a figure(). I'm running windows 10 and have tried fresh installs Matlab 2016b, 17a, and 18a. All to the same result.

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. 0.
