| 1 % APPLYMETHOD applys the given method to the input cdata. | |
| 2 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% | |

| 4 % DESCRIPTION: APPLYMETHOD applys the given method to the input cdata. | |
| 5 % | |
| 6 % CALL: pl = applymethod(d, pl) | |
| 7 % pl = applymethod(d, pl, fcns) | |
| 8 % | |
| 9 % INPUTS: d - a cdata object | |
| 10 % pl - a plist of configuration options | |
| 11 % fcns - function handle(s) for the evaluation of the uncertainty | |
| 12 % (alone or in a cell array) | |
| 13 % | |
| 14 % PARAMETERS: | |
| 15 % | |
| 16 % 'method' - the method to apply to the data | |
| 17 % 'dim' - the dimension of the chosen vector to apply the method | |
| 18 % to. This is necessary for functions like mean() when | |
| 19 % applied to matrices held in cdata objects. [default: 1] | |
| 20 % 'option' - any additional option to pass to the method. | |
