write a MATLAB code that performs following calculations$-$

Find the mean and variance of each subgroup$($ which are divided into $3$ x $3$ matrices with the help of those blue lines$)$

Mean $=1/9($sum all $9$ elements$)$

Standard Deviation $($SD$)=1/9$ SUM$[($each element $$ mean$)^2]$

Comparison: Create a table where all means and SD$$s of all subgroups are subtracted from each other

$|$M$($i$,$j$)-$M$($i$+$n$,$j$+$m$)|$ where n&m use mod $4$ arithmetic

$|$SD$($i$,$j$)-$SD$($i$+$n$,$j$+$m$)|$ where n&m use mod $4$ arithmetic

If $|$M$($i$,$j$)-$M$($i$+$n$,$j$+$m MT & $|$SD$($i$,$j$)-$SD$($i$+$n$,$j$+$m SDT Then, the two subgroups could be part of the same body. To confirm that calculate the distance: D$($i$,$ j$)=$ SQRT$\{[($i$,$j$)-($i$+$n$,$j$+$m$)]^2\}$

If D$($i$,$j DT Then, the two subgroups belong to the same body. $($blue color$)$

Simulate the prelab assignment for the following Delta threshold and color the subgroups as follows:

If D$($i$,$j DT Then, the two subgroups belong to the same body. $($blue color$)$

If D$($i$,$j DT $+25\%$ Then, the two subgroups belong to the same body. $($yellow color$)$

If D$($i$,$j DT $+50\%$ Then, the two subgroups belong to the same body. $($Orange color$)$

If D$($i$,$j$)>$ DT $+50\%$ Then, the two subgroups belong to the same body. $($red color$)$

Delta $=0,\mathrm{.}25,\mathrm{.}5,\mathrm{.}75,1$

Mean Threshold $($MT$)=\mathrm{.}25+$ Delta

SD Threshold $($SDT$)=\mathrm{.}25+$ Delta

Distance Threshold $($DT$)=2^0\mathrm{.}5+$ Delta
