MAT PLOT
MAT PLOT Statements indicate the points with one 2-dimensional array or two 1-dimensional arrays.
Let x and y be two 1-dimensional arrays with same upper and lower bounds.
`MAT PLOT POINTS:x,y
MAT PLOT LINES:x,y
MAT PLOT AREA:x,y
`
Let M be a 2-dimensional array.
`MAT PLOT POINTS:M
MAT PLOT LINES:M
MAT PLOT AREA:M
`
If the lower and upper bounds of the first dimension are 1 and n,
`MAT PLOT POINTS:M
` means
`PLOT POINTS:M(1,1),M(1,2); M(2,1),M(2,2); ... ; M(n,1),M(n,2)
`

`MAT PLOT POINTS,LIMIT n: x,y
MAT PLOT LINES,LIMIT n: x,y
MAT PLOT AREA,LIMIT n: x,y
MAT PLOT POINTS,LIMIT n: M
MAT PLOT LINES,LIMIT n: M
MAT PLOT AREA,LIMIT n: M
` With a numeric expression n, the first n elements are used.
