The trace of an n × n matrix is the sum of its diagonal elements aii, 1 ≤ i ≤ n, or traceA=∑i=1naii. The trace occurs in many matrix formulas, and we will encounter it in later chapters. It is important to note that even though AB ≠ BA in general, in fact trace (AB...

4.2.2 Covariance matrix C To find the correlation between the different dimensions d in the n samples, we first calculate the covariance or correlation matrix. The correlation matrix is needed when dimensions are not of unit length [2]. Since the feature vectors are normalized, the covariance ...
Adjusts A until a minimum value of the sum of squares of the error metrics (usually ∑(ΔE00)2 or ∑(ΔE00)2 for patches where 5 ≤ L*≤ 98 is found, using nonlinear optimization. Reports the final value of A. In applying A (generally outside of Imatest), a similar linearization...
25. Sum of Rows & ColumnsWrite a program in C to find the sum of rows and columns of a matrix.The task is to write a C program that computes the sum of rows and columns of a square matrix. The program prompts the user to input the size of the matrix and its elements, calculates...
