sir,need your valuable suggestion .how to implement comlex equations in matlab such as below.your suggestion wil be priceless to me .

[Amit]

what is the value for sigma and x?

[ashok]

sigma x=sigma y=1

Answer 1

[Shivaputra Narke]

x=-5:0.001:5;
y=-5:0.001:5;
rox=0.2;
roy=0.4;
u=1;
h=(1/(2*pi*rox*roy)).*exp(-(1/2)*((x.^2/rox^2)+(y.^2/roy^2))).*cos(2*pi*u.x);

[ashok]

sir ,can you tell me the fundementals of how to implement those type of questions.

[Walter Roberson]

The above code will generate a vector result, rather than a matrix result. It would be better to use meshgrid or ndgrid or bsxfun.

X = -5:0.001:5;
Y = -5:0.001:5;
rox = 0.2;
roy = 0.4;
u = 1;
[x, y] = ndgrid(X, Y);
h = (1/(2*pi*rox*roy)) .* exp(-(1/2)*((x.^2/rox^2) + (y.^2/roy^2))) .* cos(2*pi*u*x);
