Row-majored or Column-majored

[LeoLai930603]

I found the definition of MMult0.c and MMult1.c for multi-dimensional array storage, would you like to take a look and see whether both of them are correct?
For MMult0.c

how-to-optimize-gemm/src/HowToOptimizeGemm/MMult0.c

Lines 3 to 5 in ddab74e

	#define A(i,j) a[ (i)*lda + (j) ]
	#define B(i,j) b[ (i)*ldb + (j) ]
	#define C(i,j) c[ (i)*ldc + (j) ]

For MMult1.c

how-to-optimize-gemm/src/HowToOptimizeGemm/MMult1.c

Lines 3 to 5 in ddab74e

	#define A(i,j) a[ (j)*lda + (i) ]
	#define B(i,j) b[ (j)*ldb + (i) ]
	#define C(i,j) c[ (j)*ldc + (i) ]

As you see, the positions of i and j are inverted.

Well, MMult1.c seems not correct, I would fix it latter.
Any PR would be well received.

Fixed.
