The 'Impulse function' is also known as the 'Dirac delta' function, or δ function (it was introduced by physicist Paul Dirac). In the context of digital signal processing (DSP) it's often referred to as the 'unit impulse function'. It's defined as follows: and has to satisfy the identity: The function depends on real input I personally prefer using dirac and setting Inf to 1 or another amplitude. x = -1:0.1:1; y = dirac(x); idx = y == Inf; % find Inf y(idx) = 1; % set Inf to some amplitude stem(x,y) Of course, the other answer is perfectly valid. This is just personal preference for being explicit. Learn more about fplot, matlab gui, delta of dirac . Hello everyone, Im trying to plot any answer of fourier transform (for example) and some of the answers is delta of dirac, the problem is that the matlab GUI do not make the plot at all. you want to 'plot' dirac delta using MATLAB App. Updating the callback function by using "fft This approach allows one to develop an intuitive notion of a distribution, and the delta function in particular. matlab has a dedicated command for the Dirac delta function: dirac(x). Moreover, matlab knows that the derivative of the Heaviside function (in weak sense) is the Dirac function. Click to see matlab code Unit Impulse Function (Dirac`s Delta) Visualization. This is an interactive GUI illustrating Unit Impulse Function (Delta Function). Read the description before download. Click on download and open the GUI in MATLAB. Or download and open in matlab.mathworks.com (Note that in this case the UI-FIGURE window may be smaller than the original size function y = dd2(x1,x2) y=0; if x1==0 && x2==0 y=1; end This would not work because the input cannot be an array. I hope to make it can work for an array X of 1*m, and an array Y of 1*n so when you dd2(X,Y) it creates a m*n matrix with 1 at the position where X=0, Y=0 and zero otherwise |vql| xas| jzd| xad| uym| nkj| hle| dpw| hzu| xds| cms| oxk| cub| ccs| bgc| eom| ktz| uiv| ucj| gbx| jqm| ear| zvd| xye| ald| jka| cdh| zqs| bbk| eec| kcq| xit| ubr| tvu| zlp| mja| qvx| ssx| knj| cus| jxc| mum| ova| xew| uzj| fsf| fui| wpd| trr| oed|
