| 33 ## Algorithm: | |
| 34 ## | |
| 35 ## 1. Determine the class of x | |
| 36 ## 2. If x is of the struct, cell, list or char class, for each | |
| 37 ## argument after x, determine whether it has the same class | |
| 38 ## and size as x. | |
| 39 ## Otherwise, for each argument after x, verify that it is not | |
| 40 ## of the struct, cell, list or char class, and that it has | |
| 41 ## the same size as x. | |
| 42 ## 3. For each argument after x, compare it for equality with x: | |
| 43 ## a. struct compare each member by name, not by order (recursive) | |
| 44 ## b. cell/list compare each member by order (recursive) | |
| 45 ## c. char compare each member with strcmp | |
| 46 ## d. <other> compare each nonzero member, and assume NaN == NaN | |
| 47 ## if nans_compare_equal is nonzero. | |
| 48 | |

| 5549 | 58 |
| 6609 | 59 ## All arguments must either be of the same class or they must be |
