i want create this matrix

i want create this matrix in one ligne command and use (ones,eye...)

m =

    1.0000    3.1416    3.0000    4.0000         0         0    5.0000
    1.0000         0    3.1416    4.0000         0         0    6.0000
    1.0000         0         0    3.1416         0         0    7.0000
    1.0000         0         0         0    3.1416         0    8.0000
    1.0000         0         0         0         0    3.1416    9.0000

I'm sure it's possible to create a cryptic and unreadable one-liner to create this matrix, but why do you need that?

i want this matrix for start make program

can you help me!

[Guillaume]

Just write the matrix in your code as you've written it above. It'll be so much more readable that any one-liner and instantly clear what the matrix is.

Case in point, I'll challenge anyone reading Jesus' one liner to say what matrix it generates immediately upon reading the code.

solution :

m=[ones(5,1) pi*eye(5) (5:9)']+[diag(4,3)+diag(3:4,2)  zeros(4,3 ); zeros(1,7)]
