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...
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; ...
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 ...

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 ...
G = mupadmex('symobj::fullsubs',F.s,X2,Y2); Error in sym/subs (line 145) G = mupadsubs(F,X,Y); Error in curvature (line 41) cur = subs(k,{x y z},{A B C}); How to Get Best Site Performance Select the China site (in Chinese or English) for best site performance....
If the "-" is the first character in the string, that expression will return -1. A value less than zero is invalid as the Length argument of the Mid function. Get the position of the '-' into a variable, check that it's not Zero, and only if it's greater than zero go ahead ...

The simplest approach is to put zero in the centre. maxval = cellfun(@(x) max(abs(x)), get([h1 h2],'YData')); ylim = [-maxval, maxval] * 1.1;% Mult by 1.1 to pad out a bit set(ax(1),'YLim', ylim(1,:) );
