How to change the matrix form?

I want to draw some factor on the map.

I have a data that array like below..

longitude/latitude/data
120  /  7  /  50
120  /  6  /  90
120  /  5  /  55
121  /  7  /  57
121  /  6  /  13
121  /  5  /  16
122  /  7  /  70
122  /  6  /  19
122  /  5  /  10

As I know, in order to use m_contour or m_pcolor, I have to matrix like below

      120     121     122
7     50      57      70
6     90      13      19
5     55      16      10

How can I change the array of matrix..???

Not clear what you exacly expect, if some more clarity you can give on the problem, that would be helpful.

Thank you for answering me.

However, these data were not equal to one by one.

For example,

A = (120,6,90; 120,5,55; 121,7,10; 121,5,16) %% (longitude, latitude, value)


      120     121 
7     NaN     10       
6     90      NaN  
5     55      16  

Anyway, thank you for your help again!
