MATLAB: Change variables of a matrix with conditions

Question

Hi Everyone!

I am attempting to solve a matrix however require assistance in regards to setting conditions.

The solution is for when the temperature is being illustrated with respect to time and certain parameters have been stated. The solution requires additional steps where the parameters vary with different temperatures ranges.

regards, Snipe

X = [...
    150,156,165,174,182,191,199,207,215,222,230,238,245,252,259,266,273;...
    150,155,164,172,180,188,195,203,211,218,226,233,240,247,254,261,263;...
    150,155,162,170,177,185,192,200,207,214,222,229,236,243,250,257,263;...
    150,154,161,168,175,182,189,196,203,210,217,224,231,238,245,252,259];
V = [150,200,250]; % edges
Z = sum(bsxfun(@gt,X,reshape(V,1,1,[])),3)

and then use Z pick your conditions:

Z =
   0     1     1     1     1     1     1     2     2     2     2     2     2     3     3     3     3
   0     1     1     1     1     1     1     2     2     2     2     2     2     2     3     3     3
   0     1     1     1     1     1     1     1     2     2     2     2     2     2     2     3     3
   0     1     1     1     1     1     1     1     2     2     2     2     2     2     2     3     3
