Changing The Element Size In ANSYS® Meshing(Iluustrated Expression)
Standard deviations are very important calculations in data analysis. Because it gives very important analyses and results from given numeric data. As you know that Matlab software is very good in data analysis and mathematical manipulations like that. So you can calculate standard deviations in Matlab very easily. This article of Mechanical Base shows you how to calculate standard deviation values with Matlab coding.
We crated and ‘a’ vector and a ‘b’ matrix as shown by green arrow and red arrow above to show you how to calculate their standard deviations in MatLab.
The ‘a’ vector’s standard deviation value is calculated with std() command in Matlab as shown by blue arrow. So we can understand that there is a one standard deviation value.
Also standard deviation value of the matrix ‘b’ is calculated as shown by orange arrow with std() command in Matlab. So each row’s standard deviation value of matrices calculated separately in Matlab.
So it is very easy to calculate standard deviation values of matrices and vectors in Matlab programming.
