A matrix transposition device with which speed of processing such as a two-dimensional orthogonal transformation can be raised, wherein there is provided of a plurality of storage devices 22-0 to 22-p arranged so as to be able to input input column vectors in parallel and output output column vectors in parallel, the sum of the address ranges being enough to store all element data of the input matrix; a plurality of input selection devices 21-0 to 21-p capable of selecting one numerical value input from among a plurality of parallel numerical value inputs and inputting selected numerical value to corresponding storage devices; a plurality of address generators 23-0 to 23-p capable of designating independent addresses with respect to the storage devices; output selection devices 24-0 to 24-n capable of respectively independently selecting outputs of any storage devices; and a control device 25 which performs a control so that elements of any input row vectors are stored in different storage devices at the time of input and control so that any transposed output column vectors are output in parallel while maintaining the determined order and the order of elements in the determined column vectors in accordance with the matrix elements stored in the plurality of storage devices at the time of output.
