Policy change in how to use with OpenBLAS

Policy change in how to deal with OpenBLAS operation modes

• It was found that the operation of rindow-matlib is related to the operation mode of OpenBLAS, so we documented how to deal with OpenBLAS.

Change in policy on how to obtain CLBlast library

• Made it standard to obtain the clblast library from the Linux distribution.
• Documented that Ubuntu 20.04 does not include clblast in the Linux distribution, so there is another download method.

Complete review of type definitions

• Type definitions were applied to variables and arguments that did not have type definitions, a legacy of php7.
