Programmering med Matlab ger en introduktion till programmering och exp log Exponentialfunktionen och naturliga logaritmen. log10

The function LOG10 is similar, but always returns the common logarithm, meaning the For more information, see Run MATLAB Functions on a GPU ( Parallel

When plotting, why do we need to plot with 10*log10(pxx) instead of only using pxx? Even when I use either ways of plotting, I cant seem to emulate the yrange in the example plot (attached). The closest plot seems to be plot(fxx, 10*log10(pxx), fyy, 10*log10(pyy)) but the yrange is different. newfts = log10(tsobj) calculates the common logarithm (base 10) of all the data in the data series of the financial time series object tsobj and returns the result in the object newfts. In addition to common functions like exp and log, MATLAB ® has several other related functions to allow flexible numerical calculations. The expm1 and log1p functions compensate for numerical round-off errors in small arguments, while the reallog, realpow, and realsqrt functions restrict the range of these functions to real numbers.
