Using MATLAB, I have an array of values of size 8 rows x N columns. I need to create a matrix of the same size, that counts maximum values in each column and puts 1 in the cell that contains maximum value, and 0 elsewhere. A little example. Lets assume we have an array of values D: D = 0.0088358 0.0040346 0.40276 0.00...
I want to define a min and max methods in a Utils class. @interface Utils int min(int a, int b); int max(int a, int b); @end But I don't want to have named parameters. It would be a too heavy notation. I wanted to use the C-style definition. But then [Utils min(a, b)] as a call doesn't work. What is my problem? Thanks in advance fo...
Both arguments are guaranteed to be integers. How do I write myMax such that: myMax<1, 2>; // 2 myMax<3, 2>; // 3 ? I want this to be evaluated at compile time, not run time. (Need to then use this with sizeof for a typelist to allocate space for a variant.) Thanks! ...

When I attempt to do something like SELECT Max(ObjectId) FROM Objects; I see that in the explain-plan that this is performed by doing a sort. Now, sorting (which I guess would require something in the complexity of O(nlogn)) must be much costlier than just scanning each row and remembering the max value (which could be done in O(n)). ...
