please help to edit this matlab code

[13maruf]

a = 1:10;
b = a;
b(2,= [0, a(1: end-1)];
b(3,= [0, 0, a(1: end-2)];
B = b'

I want to generate this B matrix by a for loop...........please help me

The code which you wrote was a simpler one. See the code for generating B matric using for loop below:


b2(1)= 0;
b3(1)=0;
b3(2)=0;

for a =1:10
b1(a)=a;
if (a+1 < 11)
b2(a+1)= a;
end

if (a+2 < 11)
b3(a+2)= a;
end

end
B = [b1) b2) b3)]

what kind of a code is this???? There is no use of for loop !!! actually there is nothin to do with this code. If i just type B=[b1) b2) b(3] without any coding the result will be same...and what will u do if I say thet a=1:36???

If you want to use for a=1:36, change the n value in the code. I think now you can see the for loop in the code (I made it bold)

b2(1)= 0;
b3(1)=0;
b3(2)=0;
n = 10;

for a =1:n
b1(a)=a;
if (a+1 < n+1)
b2(a+1)= a;
end

if (a+2 < n+1)
b3(a+2)= a;
end
end
B = [b1) b2) b3)]
