Try this: Theme Copy syms x y h=10; phi= (1/h)* [1-x-y;x;y]; % if you need second function write: f2= [0 1 0]*phi; % if you need third one: f3= [0 0 1]*phi; Walter Roberson on 6 Sep 2024
WebMatlab functions operate on scalar as well as vectors To make inline function victories, the ‘ vectorize ’ keyword is used inside the function definition. In the above example suppose I want to create vector function ‘fun’ then commands will be Fun = inline ( vectorize ( ‘ x ^ 2 – 5 ’ , ’ x ’ ) It will create vector fun. Fun ( 1 : 5 ) WebVectorising it simply requires using element-wise operations: Theme Copy f = @ (X,Y) -0.0001* (abs (sin (X).*sin (Y).*exp (abs (100-sqrt (X.^2+Y.^2)/pi)))+1).^0.1; [x,y] = meshgrid (linspace (-10, 10, 49)); figure surfc (x, y, f (x,y)) grid on See the documentation on Array vs. Matrix Operations (link) and Vectorization (link) for details. 댓글 수: 9
