Comparing the performance, resize() seems to be more effient than ones().

When I initialize an array, I use a = ones(shape)*initial_val
But, I am wondering if Numpy has more efficient way. For example, a = array(initial_value, shape)
I don't know if it's any more efficient (what you have is pretty fast already), but another option is to use resize:
shape = (3,4)
initial_val = 5.0
resize(initial_val,shape)
array([[ 5., 5., 5., 5.], [ 5., 5., 5., 5.], [ 5., 5., 5., 5.]])
