Question

Problem 32. Most nonzero elements in row Given the matrix a, return the index r of the row with the most nonzero elements. Assume there will always be exactly one row that matches this criterion. Example: Input a 1 2 0 0 0 0 0 5 0 0 2 7 0 0 0 069 3 3 1 output r is 4 Solution BE MATLAB Documentation function r fullest row (a) 3 end Click submit to create a new solution.

Explanation / Answer

A)

function r=fullest_row(a)
r=1
nz=0
nz1=0
[row,col]=size(a)
for i=1:row+1
nz1=0
for j=1:col+1
if(a(i,j)!=0)
nz1=nz1+1
end
end
if(nz1>nz)
nz=nz1
r=i
end
end
end

B)

function b=back_and_forth(n)
b=ones(n)
num=1
for i=1:n+1
for j=1:n+1
if(i%2==1)
b(i,j)=num
end
if(i2==0)
b(i,n-i+1)=num
end
end
num=num+1
end
end
