The toy example showed how to create sparse matrix from a full matrix in Python. How much space do we gain by storing a big sparse matrix in SciPy.sparse? One of the real uses of sparse matrix is the huge space reduction to store sparse matrices.... In this example, [1,2] produces the first line of the matrix and [2,3] creates the second. Quick Standard Matrices [ edit ] The following built in functions can be used to quickly create some standard matrices …

**Python Multi-Dimensional Arrays or Matrices**

The scatterplot matrix, known acronymically as SPLOM, is a relatively uncommon graphical tool that uses multiple scatterplots to determine the correlation (if any) between a series of variables... And, if you need to do mathematical computation on arrays and matrices, you are much better off using something like NumPy library. Unless you don't really need arrays (array module maybe needed to interface with C code), don't use them.

## How To Make Matrices In Python

### In Python, these are handled somewhat more simply. If you have a need for more sophisticated processing than we show in this section, It uses a list comprehension to create an object for each value of j in the range of 0 to 6. Each of the objects is a list of zeroes, one for each value of i in the range of 0 to 6. After this initialization, the two-dimensional table of zeroes is printed

- In Python there is the maths module which handles the basics such as rounding, factorial and rounding functions. It also includes Power & logarithmic, trigonometry, angular and hyperbolic functions. For complex numbers, the module is cmath. These do not handle matrix operations though.
