I want to print the variable i and j values along with the input promt so that i can run the loop while getting the values but could not find something, tried fprintf but getting error "Error using input. The first argument to INPUT must be a string or character vector."

elements = input("Enter the number of elements: ");
i=1;
j=1;
while i<=elements
    while j<=2
        coordinates(i,j,1)=input(fprintf("Enter x coordinate of Element %i and node %i :",i,j));
        j=j+1;
    end
    i=i+1;
end

You can use sprintf instead of fprintf like that.

elements = input("Enter the number of elements: ");
for i=1:elements
    for j=1:2
        coordinates(i,j,1)=input(sprintf("Enter x coordinate of Element %i and node %i :",i,j));
    end
    
end
