How can i find the position of nearest number "x" in a matrix "a"

for example : a = [4 8 3; 22 12 45; 88 74 65]; x = 66; the nearest number is obviously 65 how can i find it's position? i need a list of commands that gives me the nearest number to x and it's position

Hi,

Could you find a solution for that ?

[~,pos] = min( abs( a - x ) );
nearestNum = a( pos );

+ needs a slight modification.

d = abs(a - x);
[~,pos] = min(d(:));
nearestNum = a( pos );

Ah, yes, I didn't notice the 2d nature of the matrix.

Also, if you want the position as (row,col) then

[row, col] = ind2sub( size(a), pos );

will give this.

[mahmoud fekih]

when i mean position i mean i ant it to return the column and row numbers of the minimal value of the matrix and for my example the matrix is named d1 with 35 rows and 6 columns the minimal value is "0" i need it to return to me the column and row numbers of "0" (CHEK TH PICTURE)

You can achieve this easily from combining the above, though I don't know why you complicated your question by asking about nearest value if all you really want is the minimum of your matrix!
