MATLAB PROBLEM

convert the for loop to a while loop.

vec= [1 2 3 4 5]

newVec= []

for i=vec

if i>5

new vec=[newvec, i]

end

end

end

Answer 1

vec= [1 2 3 4 5]      %vector

newVec= []             % initialize new vector 'newVec'

for i=vec                 % i will contain value of vector 'vec' for each iteration

if i>5                       % check if value of vector 'vec' is greater than 5 (>5) or not.

new vec=[newvec, i] %if yes, then push that value in the new vector 'newVec'.

end                          % end of if condition.

end                         % end of for loop

After Convertion into While Loop

vec= [1 2 3 4 5]     %vector

newVec= []            % initialize new vector 'newVec'
n=size(vec)(2)       % size of vec

i=1                         % initialize the i=1 for iteration
while i<=n             %while loop will run until i<=n

if(vec(i)>5)             % check if value of vector 'vec' is greater than 5 (>5) or not.

newVec=[newVec,vec(i)] % %if yes, then push that value in the new vector 'newVec'.

end                         %end of if condition
i=i+1                      % increment the value of i.

end                        % end of for condition

newVec                 % print the values of new vector

Note: newVec will be empty as no value of vector 'vec' is greater than 5.
