Create a program displaying number of numbers greater than 0.8 in matrix

[0.91, 0.81, 0.72, 0.74, 0.33, 0.85]
[0.91, 0.81, 0.72, 0.74, 0.33, 0.85]
[0.91, 0.81, 0.72, 0.74, 0.33, 0.85]
[0.91, 0.81, 0.72, 0.74, 0.33, 0.85]
[0.91, 0.81, 0.72, 0.74, 0.33, 0.85]

now iterate through each row and each column

for row = 0 to 4
   for column = 0 to 5
        if (columnVal > 0.8)  printLine "{row} : {column}"
   next column
next row

You should see something like :

0 : 0
0 : 1
0 : 5
...

row 0, column 0 is greater than
row 0, column 1 is great than

Just convert it to your matlab code.
