Matrices

General : in our study consider only two type of matrices :
1- One dimensional matrices.
2- Two dimensional matrices.

1- One dimensional matrices : consist of elements arranged in one column or one array each element has a constant position (location) in the matrix and this position remain constant until we change it.
• The matrix compound of name of matrix which recognized each matrix from the other and variables demonstrate the location (position) of each element :
Such as A (5) : matrix with name A and with 5 position .

• The matrix has a retain statement with general form :
No. of statement DIM name of matrix (constant)
Such as 10 DIM A (5)
• The matrix must read before apply any application on its elements.
Ex1 : Write a program in basic language to print the first and last element of one dimensional matrix consist of 5 element [5 10 15 20 25].
10 DIM A (5)
20 FOR I = 1 TO 5
30 READ A (I)
40 DATA 5,10,15,20,25
50 NEXT I
60 ? A(1) , A(5)
70 END
Ex2 : Write a program in basic language to print the element of one dimensional matrix consist of 5 element [5 10 15 20 25].
10 DIM A (5)
20 FOR I = 1 TO 5
30 READ A (I)
40 DATA 5,10,15,20,25
50 NEXT I
60 FOR I = 1 TO 5
70 ? A(I)
80 NEXT I
90 END
