Dec 9, 2016 · I have a list: l = [1,2,3] I want my output to be: m = [(1-1, 1-2, 1-3),(2-1, 2-2, 2-3), (3-1, 3-2, 3-3)] m = [[0, -1, -2], [1,0,-1], [-2,-1,0]] I wrote this function and it works fine: def matrixer(l): matrix = [] for data in l: column = [] column.append(data - l[0]) column.append(data - l[1]) column.append(data - l[2]) matrix.append(column ...

While you can create a 1D array from a generator with numpy.fromiter(), you can create an N-D array from a generator with numpy.stack: >>> mygen = (np.ones((5, 3)) for _ in range(10))

numpy.matrix # class numpy.matrix(data, dtype=None, copy=True) [source] # Returns a matrix from an array-like object, or from a string of data. A matrix is a specialized 2-D array that retains its 2-D nature through operations. It has certain special operators, such as * (matrix multiplication) and ** (matrix power).
