Look how you can print a two-dimensional array, using this handy feature of loop for And suppose you have to set elements of the main diagonal equal to 1 (that is, those elements a[i][j] for which i==j)...

If None, the arrays are flattened. Returns ----- idealfourths : {list of floats, masked array} Returns the two internal values that divide `data` into four parts using the ideal fourths algorithm either along the flattened array (if `axis` is None) or along `axis` of `data`.
- Know how to create arrays : array, arange, ones, zeros. Know the shape of the array with array.shape, then use slicing to obtain different views of the array: array[::2], etc. Adjust the shape of the array using reshape or flatten it with ravel. Obtain a subset of the elements of an array and/or modify their values with masks >>>
- Once all objects have been removed from the heap, we have a sorted array. The direction of the sorted elements can be varied by choosing a min-heap or max-heap in step one. Heapsort can be performed in place. The array can be split into two parts, the sorted array and the heap. The storage of heaps as arrays is diagrammed here.

The quartiles divide the distribution into four equal parts, called fourths. The IQR describes the middle 50% of values when ordered from lowest to highest. To calculate interquartile range we calculate 0.75 and 0,25 quartile ranges. Iterative algorithm. The definition of matrix multiplication is that if C = AB for an n × m matrix A and an m × p matrix B, then C is an n × p matrix with entries = ∑ =. From this, a simple algorithm can be constructed which loops over the indices i from 1 through n and j from 1 through p, computing the above using a nested loop:
