Create a 10×3 array A where the first column are the
x values 1
through 10, the second column are the y values where
y(x) = sqrt(x) and the third column are the z values where
z = x^2. Write the values of A to file A.dat,
one row per line. Generate a 7×11 matrix R of random
values (uniform on [0,1]), and write this matrix to file
ranm.dat.
x = [1:10]
A[1:10,1] = x
A[1:10,2] = sqrt(x)
A[1:10,3] = x^2
write\matrix 'A.dat' A
R = fold(ran([1:77]),7)
write\matrix 'ranm.dat' R
