Solution:When we multiply a vector by a scalar, the direction of the product vector is the same as that of the factor. The only difference is the length is multiplied by the scalar. So, to get a vector that is twice the length ofabut in the same direction asa,simply multiply by 2. ...
But to multiply a matrix by another matrix we need to do the "dot product" of rows and columns ... what does that mean? Let us see with an example:To work out the answer for the 1st row and 1st column:The "Dot Product" is where we multiply matching members, then sum up: (1,...
matrix multiplication is a method of finding the product of two matrices to get the result as one matrix. it is a type of binary operation. q2 how to multiply two given matrices? to multiply one matrix with another, we need to check first, if the number of columns of the first matrix...

Generally, for any two numbers a and b, the product a×b can be evaluated as a series of repeated additions where a is added by itself b times: a×b=a+a+a+⋯(b times) Long Multiplication For larger numbers, we can multiply them usingLong Multiplication. To guide us, let us work...

If the test results are still displayed in the unit of MB/s, multiply the value by 8 to obtain the actual Wi-Fi speed in the unit of Mbit/s. The theoretical Wi-Fi speed is the smaller value between the downlink speed and the wireless link speed. For example, if the downlink ...
Step 2: To complete the multiplication, we compute the dot product of each row and column of the matrix. To compute a dot product, we multiply the components and then sum the products. [a11a12a21a22]×[b11b12b21b22]=[a11×b11+a12×b21a11×b12+a12×b22a21×b11+a22×b21a21×b12+...
