The specifier GRID can be 'chebkind1', % 'chebkind2', or 'leg'. The basic difference between a vector and an array is vectors are dynamic arrays with the facility to resize itself whenever a new element is pushed inside the vector or deleted from a vector unlike arrays which have predefined lengths. Considere estos dos ejemplos: // Example 1 Foo (Bar b) { bar = b; } // Example 2 Foo (Bar b) : bar (b) { } En el ejemplo 1: Bar bar (); // default constructor bar = b; // assignment.
