MATLAB traversing an Array

Write your own script that will find the minimum element of an array. You CANNOT use the build-in function, min(). Your script will start with generating a 20 by 20 array consisting of random integers in the range [-100,100]. If will then loop through all element and find the min value of all. This is 4 based on the problem #3. In addition to finding the smallest number, this program will also count the occurrences of the smallest number. You cannot use build-in functions. You are going to traverse the array and count This is another variation of problem #3. Instead of finding the smallest number, this program will look for the two smallest numbers. (They can be of the same value). You cannot use build-in functions. You are going to traverse the array and look for the two mins.

Solution

3.

x=100*rand(20,20)

[m n]=size(x);

min=0;

for i = 1:n

for j=1:m

if (x(i,j)<min)

min=x(i,j);

else

min=min;

end

end

min

x=100*rand(20,20)

[m n]=size(x);

min=0;

for i = 1:n

for j=1:m

if (x(i,j)<min)

min=x(i,j);

else

min=min;

end

end

count=0;

for i=1:n

for j=1:m

if(x(i,j)==min)

count=count+1;

end

end

end

count

min1=0;

min2=0;

for i = 1:n

for j=1:m

if (x(i,j)<min1)

min1=x(i,j);

else

min1=min1;

end

end

min1

for i=1:n

for j=1:m

if(x(i,j)<min2 &&x(i,j)>min1)

min2=x(i,j);

end

end
