Y= log(X)returns the natural logarithmln(x)of each element in arrayX. Thelogfunction’s domain includes negative and complex numbers, which can lead to unexpected results if used unintentionally. For negative and complex numbersz = u + i*w, the complex logarithmlog(z)returns ...
Instead of creating a deep learning model from scratch, you can get a pretrained model that you apply directly or adapt to your natural language processing task. With MATLAB, you can access pretrained networks from theMATLAB Deep Learning Model Hub. For example, you can use theVGGishmodel to ...

Introduction to matlab Exponentials and Their Inverses: exp, ^, sqrt, log, log10 Electrical engineers frequently use the natural exponential function, ex. It is so common that rather than having a defined number for e and entering things as powers, matlab has its own built-in function called...
.But why just LOG not some other function like RMS?The Log helps compute thecepstral mean subtraction,which is a channel normalization technique.It is usually done when the channel varies too much.It subtracts the mean on the cepstral signal. ...
MATLAB Online에서 열기 I have an input u(t) which is a discrete function with a sampling time of .002 seconds. Similarly I have an output of the system of y(t) with the same sampling time of .002 seconds. I need to find the natural...
For each cell, a contour was used to summarize the spatial receptive field. We upsampled the spatial receptive field to single-pixel resolution and then blurred it with a circular Gaussian ofσ = 4 pixels. We extracted receptive-field contours using MATLAB’s ‘contourc’ function at 25%...
Compared with MATLAB fsolve solver, the Broyden method only needs to calculate the Jacobian matrix and its inverse form in the first iteration step, so the calculation speed is relatively fast. On the other hand, for MATLAB fsolve solver, the Jacobian matrix is built by numerical approximation,...
The Gabor filter bank was generated using the built-in Matlab function “gabor” (Matlab version 2015b). The wavelength (λ) of the Gabor filters ranged from 5–28 pixels per cycle. The orientation (θ) of Gabor filters was either 0°, 30°, 60°, 90°, 120°, or 150°. We set ...
In line with the log law wind profile, the wind speed experiences a gradual increase from 0 m/s at ground level to 1.78 m/s at the building's top edge. The collision with the building causes a modification of the components of the initial wind velocity vector, leading to changes in ...
