Using a class as a function handle

Hi all,

I'm trying to use a class as a function handle. This works perfectly in this case:

k = 8 * ones(1,3) * 1e7;
m = [3.57 3.36 3.14];
c = 0.05 * ones(1,3);

sb = @(x) shearBuilding([x(1) x(2) x(3)],m,c)
sb = sb(k)

sb =

shearBuilding with properties:

k: [3×1 double]

m: [3×1 double]

c: [3×1 double]

h: [3×1 double]

n: 3

K: [3×3 double]

M: [3×3 double]

C: [3×3 double]

phi: [3×3 double]

omega: [3×1 double]

T: [3×1 double]

gama: [3×1 double]

sb.k

ans = 3×1

80000000

80000000

80000000

But when I try to use this another class, called 'analiseSismica', that takes the first class (shearBuilding) as argument I got an error.

g = @(x) analiseSismica(sb,sis)

g = g(k)

Operator ':' is not supported for operands of type 'function_handle'.

Error in analiseSismica (line 25)
                    for i = 1:obj.estrutura.n

Why do you define a function g(x) if the inputs to g don't contain x:

analiseSismica(sb,sis) 

sb and sis, but no x.

Your definition of g does not make use of the input x. Was it supposed to be defined as below?

g = @(x) analiseSismica(sb(x),sis)

Thanks!

It works perfectly
