Column Removal

•Remove the nth column from input matrix A and return the resulting matrix in output B.

Example 1:

A = [1 2 3;

        4 5 6];

and

n = 2

then B is

[ 1 3

  4 6 ]

EXAMPLE 2:

A = 1:10;

n = 7;

B= [1 2 3 4 5 6 8 9 10];

MATLAB CODE:

clc

e=input('Enter the matrix:');

[x y]=size(e);

Y=[];

d=input('Enter the column you want to remove:');

for i=1:x

    for j=1:y

        if(j~=d)

            Y=[Y e(i,j)];

        end

    end

end

w=[];

t=1;

for i=1:x

    for j=1:y-1

        w(i,j)=Y(t);

        t=t+1;

    end

end

disp(w);

Explanation:

Sample Output:

Function:

function w=column_removal(e,d)

[x y]=size(e);

Y=[];

t=0;

k=1;

l=1;

for i=1:x

    for j=1:y

        if(j~=d)

            Y=[Y e(i,j)];

        end

    end

end

w=[];

t=1;

for i=1:x

    for j=1:y-1

        w(i,j)=Y(t);

        t=t+1;

    end

end
