Adjust Row Column

Because this row, row 1, column 2.

Row 3, column 3.

Likewise 38 is row one column two. So it's row one column two.

First row contains column names

So row 1, column 3.

And that row times this column.

Then this row times this column.

This is row 3, column 3.

Which row, which column was that?

We multiply this row vector times this column vector to get row 1, column 2, right?

Add column names as the first row

So that's in row 1 column 2.

Then finally, this row times this column.

So it's that row times this column.

You know, per row or per column.

Because this is row 2, column 2.

This is in row 2, column 1.

The ADDRESS creates a cell address. Parameter Row is the row number and Column is the column number.

looking at Row Vectors and Column Vectors. So a vector is just either one row or one column.

So now, when we're in row 2, column 1, we cross out row 2, cross out column 1.

In this example, the 1 appears once in this column, once in this column, once in this column, once in this row, once in this row, and once in this row.

So that means it's row one column one.

I cross out row 1 and column 1.

Well you cross out row 1, column 3.

So we cross out row 2, column 3.

OK, so we're in row 3, column 1.

So we cross out row 3, column 1.

So we cross out row 3, column 2.

So you cross out that row, that column.

So you cross out that row, that column.

We're going to multiply this row times this column.

I'm going to take this row times this column.

It is the 3rd row and the 4th column.

So it is essentially this row times which column?

OK, so then we're in row 2, column 3.

Well this 1 was in row 1, column 2.

So it's getting it's row information from the first matrix's row, and it's getting it's column information from the second matrix's column.

Otherwise, we keep going to the next row and the column until we've gone through each row and column for that digit.

Once we go through that row and the column, we ensure that the row count and the column count both are exactly 1.

Let me see I don't like this color at all and now we're going to multiply this row, because we're in this bottom row, we're in row 2, column 2, to row 2, column 2.

Highlight the current row, column and box in different colors

Now we're going to multiply this row times this column.

Matrix M, row one column one is, entry is one.

So it'll then be moved to row 2, column 1.
