MATRIX("INTEGER",order)

• is the size of the Integer matrix.

## Description

• This function returns the integer matrix of order 3 with the intEger elements.
• An integer matrix is a matrix whose entries are all integers.
• Normally binary matrices, the zero matrix, the unit matrix, and the adjacency matrices are the example of integer matrices.
• Here MATRIX("integer") gives integer(positive/negative) matrix of order 3.
• This integer matrices are sometimes called "integral matrices".
• Also users can get integer matrix with the positive values alone as well as negative values.
• i.e.,MATRIX("positive integer",4) gives the integer matrix with the positive value only.
• And MATRIX("negative integer",4) gives the integer matrix with the negative value only.
• Users can change order of matrices also.

## Examples

• MATRIX("integer") =-8
• MATRIX("integer",3)
 90 -28 -13 -39 32 -56 -31 -61 -6
• MATRIX("positive integer",5)
 14 56 62 70 0 19 64 10 10 33 79 86 43 99 97 48 66 58 58 87 8 30 56 20 74
• MATRIX("negative integer",6)
 -47 -44 -21 -26 -79 -73 -85 -32 -98 -45 -34 -95 -44 -59 -2 -8 -92 -10 -88 -30 -41 -14 -87 -41 -99 -91 -25 -52 -64 -16 -100 -16 -96 -9 -40 -87
