Array Functions Support
The Fractal Science Kit fractal generator Array functions are useful when working with arrays.
Array.Dim1 returns the size of an array's 1st dimension. Array.Dim2 returns the size of an array's 2nd dimension.
n = Array.Dim1(vector)
This example sets n equal to the size of the array vector; i.e., n is set to the number of items in the 1-dimensional array vector.
rows = Array.Dim1(table[,])
This example sets rows equal to the size of the 1st dimension of the array table[,] and cols equal to the size of the 2nd dimension.
void Array.ReDim(a, count)
Array.ReDim resets the dimensions of the 1-dimensional array a to count.
void Array.Copy(src, srcIndex, dst, dstIndex, count)
Array.Copy copies items from one array to another. Specifically, it copies the count items in the array src, starting at srcIndex, into the array dst, starting at dstIndex. In most cases the source and destination array will have the same type and rank but this is not required. If the source or destination arrays are 2-dimensional arrays, the index is a relative offset into the array.
This example fills m with 12 Mobius objects using the data given in the 2 arrays data1[,] and data2[,]. Since the source arrays are of type Complex, the count argument is the number of Complex elements to copy (24), and these are mapped onto 6 Mobius objects, each with 4 fields. While this type of usage should be avoided for the sake of code clarity, it can be useful in selected circumstances.
void Array.Append(a, item1, item2, ...)
Array.Append adds the given items to the end of the array. Array.AppendArray adds the items found in the array items to the end of the array. In both cases, the size of the array a is increased by the number of items. The type of the array a must must match the items you are adding. Array.AppendValue adds count copies of value to the end of the array. The type of the array a must must match the type of value.
Complex Array.Offset(array[,], row, col) = row*Array.Dim2(array[,])+col
Array.Offset returns the offset into the 2-dimensional array[,] of the item at the given row and col.
Array.Clear sets all the elements of array a to 0. If a is an array of objects, it sets all fields in all objects to 0.
void Array.Fill(a, v)
Array.Fill sets all the elements of array a (or a[,]) to v. The array a must be an array of complex values (i.e., not objects).
Array.Reverse reverses the elements of the 1-dimensional array a. a is an array complex values or objects.
Complex Array.ProductSum(z0, z1)
Array.ProductSum returns the sum of the products of the corresponding elements of the 1-dimensional arrays z0 and z1. Both arrays must have the same dimension and contain complex values (i.e., not objects).
Array.Min returns the minimum value found in the array a. The array a must be an array of real values (i.e., not Complex values or objects). Array.Max returns the maximum value found in the array a.
