I will run a set of experiments. The main method evaluated has the following signature: [Model threshold] = detect(... TrainNeg, TrainPos, nf, nT, factors, ... removeEachStage, applyEstEachStage, removeFeatures); where removeEachStage , applyEstEachStage , and removeFeatures are booleans. You can see that if I reverse the order of any of these boolean parameters I may get wrong results. Is there a method in MATLAB that allows better organization in order to minimize this kind of error? Or is there any tool I can use to protect me against these errors? Organization with a struct You could input

In the documentation for the itertools module I found this comment def dotproduct(vec1, vec2): return sum(imap(operator.mul, vec1, vec2)) Note, many of the above recipes can be optimized by replacing global lookups with local variables defined as default values. For example, the dotproduct recipe can be written as: def dotproduct(vec1, vec2, sum=sum, imap=imap, mul=operator.mul): return sum(imap(mul, vec1, vec2)) How is it?. Is there a practical noticeable speed-up (that could balance the inconvenience of the larger function signature)? In which specific conditions the use of local variables

Function prototype void foo(int n, int a[][]); gives error about incomplete type while void foo(int n, int (*a)[]); compiles. As per the decay rule int a[][] is equivalent to int (*a)[] in this case and therefore int (*a)[] should also give an error about an incomplete type but GCC seems to accept it. Is there anything I am missing? This might be a GCC bug but I didn't find anything related to it. AnT No, they are not equivalent as function parameters. They are not equivalent in exactly the same way as parameter declarations in foo and bar struct S; void foo(struct S* s); // OK void bar(struct

Can you pass a standard c# enum as a parameter? For example: enum e1 { //... } enum e2 { //... } public void test() { myFunc( e1 ); myFunc( e2 ); } public void myFunc( Enum e ) { // Iterate through all the values in e } By doing this I hope to retrieve all the names within any given enum. What would the Iteration code look like? This! public void Foo(Enum e) { var names = Enum.GetNames(e.GetType()); foreach (var name in names) { // do something! } } EDIT: My bad, you did say iterate . Note: I know I could just do the GetNames() call in my foreach statement, but I prefer to assign that type of

In one of the C++ programs, I saw a function prototype : int Classifier::command(int argc, const char*const* argv) What does const char*const* argv mean? Is it the same as const char* argv[] ? Does const char** argv also mean the same? No, it's not the same as const char *argv[] . The const prohibits modifications of the dereferenced value at the particular level of dereferencing: **argv = x; // not allowed because of the first const *argv = y; // not allowed because of the second const argv = z; // allowed because no const appears right next to the argv identifier const char*const* argv means
