volumes=data(:,end-1:end) Create a variable volumes containing the last two columns of data. p=density(2:5) y=8 x=data(y) 按列查找第8个元素 The * operator performs matrix multiplication. So, if you use * to multiply two equally sized vectors, since the inner dimensions do not agree...
Polynomial Multiplication via Convolution Create vectors u and v containing the coefficients of the polynomials x^2 + 1 and 2x + 7. u = [1 0 1]; v = [2 7]; 1. 2. Use convolution to multiply the polynomials. w = conv(u,v) 1. w = 1×4 2 7...

Instead of doing a matrix multiply, we can multiply the corresponding elements of two matrices or vectors using the .* operator. Get C = A .* B C = 3×3 1 4 0 4 25 -10 0 -10 1 Let's use the matrix A to solve the equation, A*x = b. We do this by using the \ (ba...
You mentioned, “How can I multiply these plots to convey a (qualitative) idea? “ Please see my response to your comments below. My suggestion to achieve your goal of combining these two plots while maintaining clarity would be overlaying them in a single figure. This would allow you to ...
Using the fact that a dot product between two vectors can be accomplished with the matrix multiply operator, you can just do a (row vector) * (column vector) operation on top and a sum on the bottom. E.g., If both are row vectors, then ThemeCopy E = WP * Op...
