Why we need to package these vDSP lib function???

[LenaShengzhen]

1. these functions are used for large matrix computation, every function exists dimension transformation, especially using for loop, which influences the time of processing seriously. For large matrix computation, the wasted time becomes longer more than several ten thousand times...... Using these vDSP directly is the best choices.
   I'm not joking, in fact, I accepted a project, and the person who wrote the code just used your code.
   after canceling these encapsulated function and using vDSP directly, the time reduces to 1/50000.
2. three times redundant transpose in matMul......
