How to use object array elements with sprintf?
显示 更早的评论
Hi, I'm having trouble getting sprintf to allow a string from an object property as an acceptable input.
I have a defined class that has a property 'name'. In another function I've used a loop to define 3 objects of that class into an object array called 'objArray'. I'd like to use sprintf to write a text command but I'm getting an error. I eventually want to write multiple commands with a for loop iterating over the 3 objects in objArray, but I can't figure out the syntax yet for event just the first element of the objArray...
Code:
cmd = sprintf('Object_name: %s',objArray(1).name)
Error:
Error using sprintf Function is not defined for 'cell' inputs.
I've also tried with {}...
Code:
cmd = sprintf('Object_name: %s',objArray(1).name)
Error:
Cell contents reference from a non-cell array object
Am I missing something about the sprintf syntax or should I be using a different function?
Thanks

It looks like the name property of your class does not contain a string but a cell array containing a string. You can check that with:
class(objArray(1).name)
I bet it says 'cell' instead of 'char', so either fix your property so it actually contains a string or simply extract the string from the cell with:
cmd = sprintf('Object_name: %s', objArray(1).name{1});

t = objArray(1).name;
cmd = sprintf('Object_name: %s', t{1});
