Convert the variables x1, x2,... in an anonymous function to x(1,:) ,x(2,:).....

For example: f = @(x1, x2, ... , x15) x1 .* x2 .* ... .* x15

I want get: f = @(x) x(1,:) .* x(2,:) .* ... .*x(15,:)

Answer 1

[Andrei Bobrov]

x = randi([-5 5],2,10); % this is your data

xc = num2cell(xc,2);
out = f(xc{:});

[Matt J]

I think this should be

 xc = num2cell(xc,2);

[Andrei Bobrov]

Thank you Matt! Corrected.

Answer 2

[Azzi Abdelmalek]

f=@(x) prod(x)

[chen]

Yes, but this is not a common method. If f is like: sin(x1)*x2/exp(x3)...

[Azzi Abdelmalek]

If your function is different then change it. t's not clear for me what you want

[chen]

Thank you!

For example, I mean how to convert

f = @(x1,x2)sin(x1) .* exp(x2)

to

f = @(x)sin(x(1,:)) .* exp(x(2,:))

automatically in the program.

[Azzi Abdelmalek]

You can't do conversion
