Question

1. Write a MATLAB function in a separate file and name it mat_function, this function should accept the matrix mat_in as its first input and the real number num_in as the second input, and return the following three outputs: I. Replace each element in mat_in that is greater than num_in by 1 and each element that is less than num_in by zero to get the new matrix mat1_out. II. Replace the diagonal of mat1_out by the diagonal of mat_in while keeping all the other elements of mat1_out to get the new matrix mat3_out.

[mat1_out,mat3_out]=mat_function(randi([1,5],3,3),3)

function [mat1_out,mat3_out]=mat_function(mat_in,num_in)
mat1_out=[];
for i=1:size(mat_in,1)
for j=1:size(mat_in,2)
if(mat_in(i,j)>num_in)
mat_out(i,j)=1;
elseif(mat_in(i,j)<num_in)
mat_out(i,j)=0;
else
mat1_out(i,j)=mat_in(i,j);
end
end
end
mat3_out=mat1_out;
for i=1:size(mat1_out,1)
for j=1:size(mat1_out,2)
if(i==j)
mat3_out(i,j)=mat_in(i,j);
end
end
end
end
