h = fspecial('motion', len , theta ) returns a filter to approximate, once convolved with an image, the linear motion of a camera. len specifies the length of the motion and theta specifies the angle of motion in degrees in a counter-clockwise direction. The filter becomes a vector for horizontal and vertical motions.

svd (MATLAB Functions) The svd command computes the matrix singular value decomposition. s = svd(X) returns a vector of singular values. [U,S,V] = svd(X) produces a diagonal matrix S of the same dimension as X , with nonnegative diagonal elements in decreasing order, and unitary matrices U and V so that X = U*S*V'.

The fscanf() function is used to read formatted input from the file. It works just like scanf() function but instead of reading data from the standard input it reads the data from the file. ... On success, this function returns the number of values read and on error or end of the file it returns EOF or -1 .

The FFT operates by decomposing an N point time domain signal into N time domain signals each composed of a single point. The second step is to calculate the N frequency spectra corresponding to these N time domain signals. Lastly, the N spectra are synthesized into a single frequency spectrum. separate stages.

FSUIPC now supports FSX: Steam Edition. ... FSUIPC is a software tool which allows third-party programs to interact with the 'inner workings' of FSX and also gives users access to the many variables present in Microsoft's Flight Simulator. A number of third-party software programs depend on FSUIPC to functional correctly.

fftshift (MATLAB Functions) Y = fftshift(X) rearranges the outputs of fft , fft2 , and fftn by moving the zero-frequency component to the center of the array. It is useful for visualizing a Fourier transform with the zero-frequency component in the middle of the spectrum.

Writing a file using fwrite fwrite is defined as. int fwrite ( const void * array, size_t size, size_t count, FILE * stream ); fwrite function writes a block of data to the stream. It will write an array of count elements to the current position in the stream. For each element, it will write size bytes.

tf2ss converts a transfer function representation of a given system to an equivalent state-space representation. ... tf2ss also works for discrete systems, but you must pad the numerator with trailing zeros to make it the same length as the denominator. The tf2ss function is part of the standard MATLAB language.
