WebThis ensures x is a row vector. It is useful when you are unsure of the size or shape of an input but you need it to be a row vector. x (:) forces x to be a column vector and the transpose (') makes the column vector a row vector, as Cris' answer shows. The reason you can't just do the transpose x' is because x might already be a row vector or ...

To solve such complex numbers, we have to know the value of i, which we can conclude from the expression, i2 = -1. If we take the square root on both sides, we get, √ i2 = √-1. Or i = √-1. Therefore, the value if ‘ i’ is √-1, which we cannot define, therefore, it is called an imaginary number. the race by lauraine snelling amazonthe race boatWeb32 rows · List of all mathematical symbols and signs - meaning and examples.
