So, if c = einsum("i,j", a, b) +then c[i,j] == a[i]*b[j], but if c = einsum("j,i", a, b) +then c[i,j] = a[j]*b[i]. + +Alternatively, you can control the output order or prevent +an axis from being summed/force an axis to be summed by providing +indices for the output. This allows us to turn 'trace' into +'diag', for example. +- diag(a) -> einsum("ii->i", a) +- sum(a, axis=0) -> einsum("i...->", a) + +Subscripts at the beginning and end may be specified by +putting an ellipsis "..." in the middle.

This allows the "innate type and shape" +of Python list-of-lists to be discovered without +actually converting to an array. + +In some cases, such as structured arrays and the __array__ interface, +a data type needs to be used to make sense of the object. When +this is needed, provide a Descr for 'requested_dtype', otherwise +provide NULL. This reference is not stolen. Also, if the requested +dtype doesn't modify the interpretation of the input, out_dtype will +still get the "innate" dtype of the object, not the dtype passed +in 'requested_dtype'. + +If writing to the value in 'op' is desired, set the boolean +'writeable' to 1.
