Alogrithm:

Multiplication of two matrixes:

Rule: Multiplication of two matrixes is only possible if first matrix has size m X n and other matrix has size n x r. Where m, n and r are any positive integer.

Multiplication of two matrixes is defined as

Where 1 i  m and 1 ≤ j  n

For example:
Suppose two matrixes A and B of size of 2 x 2 and 2 x 3 respectively:

1. i cant understand pointers can you send a file so that i can under stand
thanks for the service i hope that you can send me dat file to my id
rockingstar2008.kumar@gmail.com

2. Can you post the program "
Mutiplication of two matrices using pointers", if possible please email to sindhurao01@gmail.com

3. is that any easy method to solve this problem actuallu i less understand

4. can you please send me the program for "multiplication of two matrices" on my e-mail:
"kr.ssshrey@gmail.com"

5. thanks man you're a saviour

6. please send me structures,unions,files notes and important programs

7. thnxxxxxxxxxxx

8. hey plzz email all c program from function plz do its my xam or else kt

9. Thanks frnd..

10. can i knw wat r function ?

1. Great qsn..

11. pls get me a program to swap two numbrs wdout using 3rd variable using function concpt...

12. Thanks a lot

13. please send me a program to accept the characters from user

14. can u give me program to make search engine in c language or if possible then send me on
spaxyz1@gmail.com

15. thanks

16. nice one ... was asked this in an interview where I goofed up ...good logic

17. Matrix multiplication-prove using c prog multiplication is possible only if(r1==c2) and the order of resultant matrix will be c1*r2

18. Broad cocept of multiplication of matrices

19. Please send all c prg to my email id shaijumonskv@gmail.com

20. Thank You

21. nice programs

22. superb

23. pls brief the algorithm and flowchart. correct the spelling for algorithm pls

24. can you pls solve my problem i am a cse student i don't understand how to solve a problem related to c program i cannot understand the program logic pls give me some advice. my mail id magdalen1995.selvi@gmail.com

25. i am csc student plz give me the flow chart for this source code

26. can you plz send me a program to multiply and divide two matrices simultaneously??my mail id is lidros1@gmail.com

27. Good

28. Thank you so much for the program...

29. write a c program to display the elements in the matrix from any starting point it should travel upside down and also want to end at starting point.
pls help me

30. can u pls send me the program to multiply two matrix using pointers

32. sir can u plz write down this program for me:-
WRITE DOWN A C++ CODE TO ADD SUBTRACT AND MULTIPLY TWO MATRICES OF 2 DIMENSIONAL ARRAY USING FUNCTIONS .

33. cooll.dude.....

34. write a program in c language which multiply square two matrices using divide and conqor algorithm
NOTE: you are not create new matrix

35. my g mail id is sakhawatbalti.raja@gmail.com

36. please send me the multiplication of two matrices A and B with dimentions 3 into 4 and 4 into 3
