hello,

im working on a project in matlab for course i am doing in college .

i want to build a function that Requests and receives from the user the dimensions of the sampled matrix until a proper value is obtained (Two inputs) (the dimensions should be between 4 and 10 lines) inclusive (and between 12 and 7 columns (Including). The input needs to note what is the permissible range for input values. Proper by this setting, issue a message explaining exactly what the problem is and request a new input.

I might be far for the correct code but that's cause i am new at this

thank you for any help !!

infinite loop
if true , break
else input again and break

Note: (m condition goes here) && (n condition goes here), You have m and n swapped rectify it.

function [R, C]=MD(m,n)
while m<4 || m>10 || n>12 || n<7
        disp('Wrong dimensions are entered: Enter new dimensions!  m = [4, 10], n=[7, 12]')
        m= input('Enter the number of rows:         ');
        n = input('Enter the number of colmuns:    ');
end
disp('Well Done!')
R = m;
C = n;
fprintf('You have entered: %.0f Rows  and %.0f Columns \n', R, C)
end

Thank you amigo!!! But its not working[ Not enough input arguments.

Error in MatrixDimInput (line 2)

while m<4 || m>10 || n>12 || n<7

I would put your input into a continuous while loop and break the loop when the condition is met.

function [m,n]=MatrixDimInput()
while 1
    m=input('Enter the number of rows of the matrix: ');
    n=input('Enter the number of columns of the matrix: ');
    if m<13&&m>7&&n<10&&n>4
        break;
    end
    disp('wrong dimensions try again');
end
end
