Each element of rowDist specifies the number of rows in the subarray that is in the …Z and P are the zeros and poles (the roots of the numerator and denominator, respectively).K is the gain of the factored form. For example, G(s) has a real pole at s = –2 and a pair of complex poles at s = –1 ± i.The vector P = [-1-1i -1+1i …This MATLAB function performs quaternion element-wise division by dividing each element of quaternion A by the corresponding element of quaternion B.b = regress (y,X) returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X. To compute coefficient estimates for a model with a constant term (intercept), include a column of ones in the matrix X. [b,bint] = regress (y,X) also returns a matrix bint of 95% confidence ...If the first condition is false, then matlab checks if b>=c. If b is larger than or equal to c, then it is used to divide and then its position (second) is used to index, and the rest of the values (first and third) are 0. So for example, if you divide 1 by [2; 4; 4], you will return 0 0.25 0.Check that the two matrices can be multiplied together. To multiply two matrices together, the number of columns in the first matrix must equal the number of rows in the second matrix.
