The array index in C starts with 0 because the name of an array is a pointer that is a reference to a memory location and the index is used as an offset. Hence, an expression *(arr + n) or arr[n] locates an element n-locations away from the starting loca
Mouse Problem: Why do I keep getting the error message, "Array indices must be positive integers or logical values."?loop, then mod(i+1,5) is mod(4+1,5) which is mod(5,5) which is 0. You then try to use that 0 to index x.
indexing, which can be useful when working with conditional statements. For example, say you want to know the values of "A" that is larger than 7. Use the > operator to return a logical array whose elements are logical 1 when an element in "A" is larger ...
In this code, you are creating a 3x3 array arr_1 storing the values from 1 through 9. Then, you create a 2x2 slice of the original array storing from the second value to the end in both dimensions, arr_2. Notice that the Python indexing is 0-based, so the second element has the...
I just tried writing a class called JumboArray that used long for indexing. It used a three dimensional array: - the top level dimension had a size of length() / Integer.MAX_VALUE / Integer.MAX_VALUE, rounding up to 1 if it was 0. - the dimension below that had a size of (le...
For now, the index array contains only zeros. Assigning values to thexvector in an optimal way, as in method 1, takes0.094316seconds. Now, the index vector has to be read from the memory so that it can be used in indexing. That is additional0.094316/2seconds. Recall that inx(...

Indeed; an array, conceptually, is an atomic list of things - indexing into it, as opposed to operating in the whole list, is a smell. Alternatively, the array might be being used as a tuple - in which case, it has a structure, and “destructuring” it is the appropriate semantic. ...
