MATLAB Online에서 열기 Hello Sachin, Good idea to work this out as you are doing. I believe that the problem occurs with the very first line of code. For a correct N point fft, the array spacing in x should be 2*pi/N. However, with the l...
MATLAB Online에서 열기 If you have the Image Processing ToolBox you can use the function PADARRAY. For example if I wanted to pad 2 zeroes around the matrix: A = [1 2; 3 4]; B = [5 6; 7 8]; C = cat(3,A,B);% 3D matrix ...
Open in MATLAB Online You could write a function for this purpose: functionImgP = ImagePad(Img, xPad, yPad) siz = size(Img); ImgP = zeros(siz + 2 * [XPad, YPad], class(Img)); ImgP(XPad + 1:XPad + siz(1), YPad + 1:YPad + siz(2)) = Img; ...

how to zero pad a matrix?編集済み:Star Strider
There are a few reasons why you might want to zero pad time-domain data. The most common reason is to make a waveform have a power-of-two number of samples. When the time-domain length of a waveform is a power of two, radix-2 FFT algorithms, which are extremely efficient, can be ...
Open in MATLAB Online If you have the Image Processing Toolbox, you can use padarray. If not, ThemeCopy paddedM = zeros(512:512); paddedM(129:384,129:384) = M; (assuming you want equal padding on all sides, and I did my math right). ...

Implementation details: The Sylvester equation in Eq. (6) is solved by a MATLAB built-in function, which takes only around 5 seconds on an Intel Core i7 CPU at 3.40GHz. The number of rows of matrices Wx and Wz is equal to the number of seen classes. We choose the Method Ba et al...
