WebNumPy’s main object is the homogeneous multidimensional array. It is a table of elements (usually numbers), all of the same type, indexed by a tuple of positive integers. In Numpy dimensions are called axes. The number of axes is rank. For example, the coordinates of a point in 3D space [1, 2, 1]is an array of rank 1, because it has one axis.

NumPy, like Python, numbers indices from 0; a[0] is the first element. MATLAB’s scripting language was created for linear algebra so the syntax for some array manipulations is more compact than NumPy’s. On the other hand, the API for adding GUIs and creating full-fledged applications is more or less an afterthought. photo of cheslie kryst\u0027s mother
