Question

Need help with MatLab coding (Will medal)

I'm trying to code for Pascal's triangle (quick Google will explain it). My code is:

function[P]=Pascales(n)
for i=1:n
B(i, 1)=1
for i=2:n
for j=2:n
B(i,j)=B(i-1,j)+B(i-1,j-1)
end
end
end

But I keep getting the error:

Index exceeds matrix dimensions.

Error in Pascales (line 7)
B(i,j)=B(i-1,j)+B(i-1,j-1)

Please help.

Answer 1

Are there supposed to be commas between i and j inside the parentheses?
