Two studies were performed for this analysis. We compared the usability and efficiency of IDL to that of Matlab to determine if IDL is a viable substitute. This paper reports on work done while working for the REU Site: Interdisciplinary Program in High Performance Computing at the University of Maryland, Baltimore County.Ĭreated by Exelis Visual Information Solutions, IDL (Interactive Data Language) is a commercial package used for data analysis.
Therefore, we conclude that Octave is the best viable alternative to Matlab because not only was it fully compatible with Matlab, but it also exhibited the best performance.
Both FreeMat and Scilab exhibited some incompatibility with Matlab and some performance problems in our tests. After performing both usability and performance tests on Matlab, Octave, FreeMat, and Scilab, we conclude that Octave is the most usable and most powerful freely available numerical computation package. We compare the packages under Linux on one compute node with two quad-core Intel Nehalem processors (2.66 GHz, 8 MB cache) and 24 GB of memory that is part of an 86-node distributed-memory cluster. We investigate whether these packages are viable alternatives to Matlab for uses in teaching and research.

Octave, FreeMat, and Scilab are free numerical computational packages that have many of the same features as Matlab. The horizontal line of the matrix is called row.Matlab is the most popular commercial package for numerical computations in mathematics, statistics, the sciences, engineering, and other fields. So this address of the elements of the matrix is given by two term So we can know every element if someone give us the address of the element. Just like out home address relates to the person who lives in the address. Now 1,2, 3 are elements of the matrix and every element have a address to recognize the element. Matrix elements should be inside a third brackets like but here let it make simple for writing here and i will write it like | 1 2 3| Freemat sees things like its a matrix, so have to know a little about matrix if you are really interested in using Freemat.
The first element signify the number of rows and the second signify the number of columns.įreemat provides a matrix environment of numerical analysis. This contain the specifications for 'rand' command i.e a 3X3 matrix. After a command you don't need to use the square brackets but use first brackets ( ). So we have 3 row staked together making it a 3X3 matrix. Here we have created 3 row matrices and a ' ' in between them to make the program understand that next segment belong to the next row. Square bracket is need and every element is given an address to identify it. We assigned another name to a column matrix. In creating row matrix we just separate the element with blank spaces only. If we are defining Matrix we have to use square brackets and inside the brackets we have to write the elements. Its an array and give a location number to all the elements of the matrix. Its very easy to create matrix in Freemat.Ī is the name of the matrix and the value of all the elements are stored in the variable A.

Now how to create them and later work with them. By now we have come to know some basics about Matrix.
