Date :The MatrixWe define a matrix as any rectangular array of numbers.Examples of matric may be formed From the cofficientsand constants of a system of linear equations : : that is,2x - 4y : 73x +Y =16Can be written as follows2-473 1 16The numbers used in the matrix are callid elements - In theexample given, we have theree columns and two rows ofelements. The number of rows and columns are used columnsare used to determine the dimensions of the matnix. InOur example, the dimensions of the matrix are 2 x3, having2 rows and 3 coloums of elements. In general the dimensionsof a matrix which have is rows and n columns is calledan mxn matrix, Example of matrices and thair dimonsionsare as follows . :/722x348I76 2 - 3x235323x1I
