I have a cell array A 2x100. Each element of A is a 6x1 matrix. If B is a 101x6 matrix. I want to multiply each raw of the last 100 raws of B with every element of A. Thus at the end it should deliver a 2x100 cell array of scalars. I 've tried ...
but once again i request you to answer me how to multiply L(:,:,k,i).*M(:,:,k,i); without loop for i=1:N & for k=1:N. or L(:,:,k,:).*M(:,:,k,:) 댓글을 달려면 로그인하십시오.이 질문에 답변하려면 로그인하십시...

In NumPy, slices of arrays are views to the original array. This behavior saves memory and time, since the values in the array don’t have to be copied to a new location. However, it means that changes that you make to a slice from an array will change the original array. You should...

Multiply the factors to recreateA. With the two-input syntax,luincorporates the permutation matrixPdirectly into theLfactor, such that theLbeing returned is reallyP'*Land thusA = L*U. Get L*U ans =3×310 -7 0 -3 2 6 5 -1 5 ...
For non-scalar A and B, the number of columns of A must be equal to the number of rows of B. A scalar can multiply a matrix of any size. 4 .* Array multiplication. A.*B is the element-by-element product of the arrays A and B. A and B must have the same size, unless one...
To multiply them together we write x = d*p'. Note that the symbol ' transposes the row p into a column so that the multiplication is valid. The result, x, is a scalar. Many practitioners use .' to indicate a transpose. The reason for this is discussed in Section 1.4. Assuming the...
Do not multiply a 2x1 array with a 4x1 array. Check your code as you write it. functionShaft_deflection_calculation(E,F,x_f,x_r,x_s,d) E = 30*10^6; F = [20; 45]; x_f = [5.25; 5.25]; x_r = [0.5; 10]; x_s = [1;2;3;4;5;6]; ...
