swift documentation says. unlike objective-c initializers, swift initializers not return value. please explain below syntax. let instanceofstring = string() it initialize string object calling initializer , return it. value assigned instanceofstring . isn't it? the swift documentation refers syntax of type's init methods. the syntax omits return type in signature , method not contain return statement: init() { } obviously the call of initializer ( string() ) return value. difference objective-c init method in pure swift types not free return different object target of method—it's implicitly allocated instance of target type. the exception it's possible return nil in failable initializers.

i trying implement example given in eigen tutorial pseudocode. far understand, illustrates recommended method filling sparse matrix, provided number of non 0 entries per column known. the pseudocode found under header " filling sparse matrix "and written follows: 1: sparsematrix<double> mat(rows,cols); // default column major 2: mat.reserve(vectorxi::constant(cols,6)); 3: each i,j such v_ij != 0 4: mat.insert(i,j) = v_ij; // alternative: mat.coeffref(i,j) += v_ij; 5: mat.makecompressed(); // optional my attempt transform c found below. have (hopefully) written vee() such, create 2500 non-zero elements per column. therefore 2500 should correspond 6 in example. set 3000 test make.compressed well. unfortunately, don't understand behaviour of programme. i=0...3000 in seconds, stuck minutes. goes 6000 , stuck again minutes. why , how better performance? furthermore, memory usage strange. can see @ times

imagine connection person x address (manytomany). user wants add person same address, has previous person. person address address +------------------------+ +-------------------------------+ | person_id | address_id | | id | postcode | city |... | +------------------------+ +-------------------------------+ | 1 | 1 | | 1 | 15800 | new york |... | | 2 | 1 | | 2 | 25385 | london |... | +------------------------+ +-------------------------------+ person +------------------+ | id | name | ... | +------------------+ | 1 | jack | ... | | 2 | peter | ... | +------------------+ is there automatic way to: check if same address exists. if add connection instead of create duplicate address. when update jack (from example) , address, add new address instead of updating address of peter. when delete check if there address connected person. if not delete address, otherwise delete connection
