fix the soulation pleaase

Please any one can fix this for me please

>> [x,y]=meshgrid(-pi:0.1:pi,-pi:0.1:pi);

>> z=exp(-x.^2*y.^2).*sin(x*y);

>> mesh(x,y,z); axis image;

>> options= {,'interpreter','latex','fontSize',14}; % Use LATEX for labeling

>> xlabel('$x$-axis',options{:}); ylabel('$y$-axis',options{:});

>> title('ASCENT',options{:});

>> hold on

>> p=[-1.6,-1.6];

>> plot(p(1,1),p(1,2),'or','MarkerSize',10);

>> x=p(1,size(p,2));

>> y=p(2,size(p,2));

Index in position 1 exceeds array bounds (must not exceed 1).

>> y=p(1,size(p,2));

>> fx=-2*x*y^2*exp(-x^2*y^2)*sin(x*y);

>> fy= -2*x^2*y*exp(-x^2*y^2)*sin(x*y);

>> p=[p p(:,size(p,2))+0.2*[fx;fy]]; % the only line that really maters

Error using horzcat

Dimensions of arrays being concatenated are not consistent.

[Walter Roberson]

I already explained this to you.

You need to decide whether your y coordinates are to be stored in the second column of the variable, or in the second row of the variable.

Answer 1

[Devineni Aslesha]

In the provided code, the size of p is 1x2. However, the size of p(:,size(p,2))+0.2*[fx;fy] is 2x1. While concatenating horizontally, all the arrays should have the same number of rows. So, it can be concatenated as shown below.

p = [p p(: , size(p,2))+0.2*[fx fy]];
