what are ./ and .* are used for

Answer 1

[Walter Roberson]

./ and .* are element-by-element division and multiplication, respectively.

[1 2 3] ./ [4 5 6]

means

[1/4 2/5 3/6]

and

[1 2 3] .* [4 5 6]

means

[1*4 2*5 3*6]

The operations that do not have the dots in them, / and * are instead matrix algebra division and matrix algebra multiplication
