MATLAB求矩阵每一行之和
急求
r=[2015,1245,962,730,566;375,263,105,84,73;25,10,5.6,3.4,2.9;7.2,5.3,5,1.3,0.1;0.47,0.015,0.013,0.005,0;7.6,6.2,1.7,0.5,0.23;0.0095,0.0032,0.00085,1e-006,0;0.295,0.012,0.0093,0.0032,0;0.394,0.0625,0.0053,0.0006,0;153,132,75,75,0;]

A=rand(3,4)
A =
0.9501 0.4860 0.4565 0.4447
0.2311 0.8913 0.0185 0.6154
0.6068 0.7621 0.8214 0.7919
>>sum(A,2)
ans =
2.3373
1.7564
2.9823
自己按照我这个格式弄一下吧
