Example 1

//@version=6
indicator("`matrix.swap_rows()` Example")// For efficiency, execute this code only once.
if barstate.islastconfirmedhistory // Create a 3x2 matrix with ‘na’ values.
var m1 = matrix.new<int>(3, 2, na) // Fill the matrix with values. matrix.set(m1, 0, 0, 1)
matrix.set(m1, 0, 1, 2)
matrix.set(m1, 1, 0, 3)
matrix.set(m1, 1, 1, 4)
matrix.set(m1, 2, 0, 5)
matrix.set(m1, 2, 1, 6) // Copy the matrix to a new one.
var m2 = matrix.copy(m1) // Swap the first and second rows of the matrix copy. matrix.swap_rows(m2, 0, 1) // Display using a table.
var t = table.new(position.top_right, 2, 2, color.green)
table.cell(t, 0, 0, "Original matrix:")
table.cell(t, 0, 1, str.tostring(m1))
table.cell(t, 1, 0, "Swapped rows in copy:")
table.cell(t, 1, 1, str.tostring(m2))
