Just wondering if it is possible to do the following in a single line,

Say I have an array of Object A's lets call the array O, and each object has a parameter x...

Now I have another array "update_x" (of the same size), which contains all the values which I want to set the values of O.x's to.

so I want to do a single line O(i).x = x(i)

I assumed it is something O(:).x = update_x(:), but that isn't the correct answer.

Any help much appreciated.

If update_x where a CELL array, you could do it like this

[O.x]=update_x{:}

or if you have an older version of MATLAB

[O.x]=deal(update_x{:})

If you're stuck with update_x not being a cell array, you should really invest in making the following function one of your permanent utilities

function varargout=dealcell(X)

varargout=num2cell(X);

end

Then you can do something virtually the same as above

[O.x]=dealcell(update_x)
