The maximum standard deviation of the each element was 7.6253 × 10−3 Ω, indicating that the standard deviation was under 8 × 10−3 Ω.
If X is a matrix, std(X) returns a row vector containing the standard deviation of the elements of each column of X.
As the noise is present in microarray datasets, the deviation from actual value and expected value of each element in the dataset also exists.
The noise vectors were computed by assuming that the real and imaginary parts of each element of the vector are independent and identically distributed Gaussians with a standard deviation proportional to the expected signal intensity [ 21].
A second diagnostic is the difference between the G and the S matrix, which can be expected visually or summarized in a suitable statistic such as the standard deviation of element wise differences σ.
To characterize these distributions, we then made use of the mean value and standard deviation of each distribution, leading to a total of 10 quantitative features (a 10-element vector) to represent each sample.
Average concentration values, minimum and maximum levels and standard deviation of the elements determined in the PM2.5 fraction are shown in Table 2 whereas the correlation coefficients of the analyzed elements are reported in Table 3.
In the temperature calculation of fuel elements, several uncertain factors are considered carefully, including non-uniform burnup, power distribution deviation, manufacture deviation of fuel elements, graphite balls mixed with fuel balls in the core, calculation deviation of heat transfer and so on.
If X is a multidimensional array, std(X) is the standard deviation of the elements along the first non-singleton dimension of X. S = 1 n - 1 ∑ i = 1 n X i - X ¯ 2 1 2 S = 1 n ∑ i = 1 n X i - X ¯ 2 1 2 X ¯ = 1 n ∑ i = 1 n X i. B = any(A) tests whether any of the elements along various dimensions of an array is a nonzero number or is logical 1 (true).
Variance minimization methods : define clusters as blocks in the matrix with minimal deviation of their elements.
