# Write a c program to implement matrix chain multiplication

Both the correctness and the speed-up of the program due to parallelism will be considered as well as the degree to which the program handles error conditions. The program must conform to a specific prototype and generate output in the specified format. Matrix-Chain Multiplication • Let A be an n by m matrix, let B be an m by p matrix, then C = AB is an n by p matrix. • C = AB can be computed in O(nmp) time, using traditional matrix. Matrix Chain Multiplication in C and C++ Here you will learn about Matrix Chain Multiplication with example and also get a program that implements matrix chain multiplication in C and C++. Before going to main problem first remember some basis. In this paper we report on the development of an efficient and portable implementation of Strassen's matrix multiplication algorithm for matrices of arbitrary size. A. Tsao, and T. Turnbull. Strassen's algorithm for matrix multiplication: Modeling, analysis, and implementation. arrays and the parallelization strategy for the loops in a.

I've used Python 2. It is very simple to use. Add these two lines at the top of the ikj-script: By the way, it is useless to combine Psyco and NumPy. It gets a little bit faster 1 minute and 28 secondsbut this could also be a random effect.

If you execute it many times, you will see that the execution time is never the same. Java I am using this Java version: If you use Vector instead of ArrayListyou get these results: The first 10 results were only implementations of the ijk-algorithm.

Although the ijk-algorithm is very easy, most of the results were only questions where people tried to implement it.

They also have a documentation. You might need to install this for the following code: Conclusion for Java Java execution times for matrix multiplication You should definitely know if some Java-datastructures are synchronised or not. Boost If you want to compile these scripts, you might have to install the boost libraries first.

On Ubuntu you can enter: Blitz This is a great example of useless library. I've installed the library: Well, I have no clue how I could exactly use it!

See my StackOverflow Question: I was very astonished, that the library Boost is slower actually MUCH slower than my simplest approach was. Conclusion If I want to create a working piece of code in a minimum amount of time, I will always take Python.

It has been very easy to solve this task with the given restrictions. I was searching for libraries and found some, but the search results were not satisfying.C program for matrix multiplication. 3. Write a program for matrix multiplication in c.

Write a c program to find out transport of. Note: This C program to multiply two matrices using chain matrix multiplication algorithm has been compiled with GNU GCC compiler and developed using gEdit Editor and terminal in Linux Ubuntu operating system.

For example, suppose A is a 10 × 30 matrix, B is a 30 × 5 matrix, and C is a 5 × 60 matrix. Then, (AB)C = (10×30×5) + (10×5×60) = + = operations A(BC) = (30×5×60) + (10×30×60) = + = operations. Clearly the first parenthesization requires less number of operations. Matrix chain multiplication is one of the most likely problems that can be solved using dynamic programming. Algorithm 1 has an inherent parallelism which suits for parallel implementation on the available parallel hardware system.
