Shift bits specified number of places

`intout = bitshift(A,k)`

`intout = bitshift(A,k,assumedtype)`

returns `intout`

= bitshift(`A`

,`k`

)`A`

shifted
to the left by `k`

bits, equivalent to multiplying
by 2

. Negative values
of ^{k}`k`

correspond to shifting bits right or dividing
by 2

and rounding
to the nearest integer towards negative infinity. Any overflow bits
are truncated. ^{|k|}

If

`A`

is an array of signed integers, then`bitshift`

returns the arithmetic shift results, preserving the signed bit when`k`

is negative, and not preserving the signed bit when`k`

is positive.If

`k`

is positive, MATLAB^{®}shifts the bits to the left and inserts`k`

0-bits on the right.If

`k`

is negative and`A`

is nonnegative, then MATLAB shifts the bits to the right and inserts`|`

`k`

`|`

0-bits on the left.If

`k`

is negative and`A`

is negative, then MATLAB shifts the bits to the right and inserts`|`

`k`

`|`

1-bits on the left.
