%supposing a is your matrix 
[value, index]=max(max(a))

The most accurate answer to your question is: "122.9672" at (1,1). But your "matrix" has no rectangular shape.

A more general answer can be found here: Answers: finding-the-row-and-column-number-in-a-matrix

And explicitely again:

A = rand(10, 10); % Example data.
[rowValue, rowIndex] = max(A, 1);
[Value, col] = max(rowValue);
row = rowIndex(col);
