Matrix function -- problem with the defi

Hi!

I wrote this code where Y is a cell array (actually is a matrix [y1; y2; y3] and F is a matrix that I would like to be like the function of Y -- I mean if Y = [y1; y2; y3] -> F(Y) = [1; y3; f(y1, y2, y3)] where f - another function.

How can I realize this in Matlab? Unfortunely this code does not work in an appropriate way. ;(

Thanks!

Y = @(y1, y2, y3) {@(y1) y1; @(y2) y2; @(y3) y3}; 
F = @(Y) [1; Y(3); f(Y(1), Y(2), Y(3))]

Hi Mikl,

To solve your problem with defining the function F(Y), you can use MATLAB's function handles and anonymous functions. These resources will guide you on how to define and work with them:

• https://www.mathworks.com/help/matlab/matlab_prog/anonymous-functions.html

I hope this helps!

function Y=F(Y,f)
y3=Y(3,:);
Y(2:3,:)=[y3;f(Y(1,:),Y(2,:),y3)];
Y(1,:)=1;
end
