The type ofmatrixshould be a valid MATLAB matrix or multidimensional array. For example, let’s find the sum of all the elements present in a given matrix. See the code below. m=[261;171918];sumOfElements=sum(sum(m)) In the code above, we initialize the matrixmwith values. This matr...
The function is used to enumerate the mean value of each column of the matrix, the specific effect is shown below: 5.sort函数(sort function)该函数用于对每列数值进行排序,具体效果如下图所示: The function is used to sort the values in each column, the specific effect is shown below: ...
NowM2is on top of the matrixM1(1:3,3:5). Compute the element-by-element products and sum them. The answer should be 1×8+7×3+13×4+8×1+14×5+20×9+15×6+16×7+22×2=585. [r2,c2] = size(M2); CC = sum(sum(M1(0+(1:r2),2+(1:c2)).*M2)) ...
