plot3, how to plot

i have Z={1x1 cell} {1x7 cell} {1x2 cell}

          for j=1:k2
           for d=1:length(Z{j})   

              B=Z{j}{d}

              if (j==j)
                  plot3(B(1),B(2),B(3),'*b')

              end
          end
      end

I want to plot if each j had other color

Thanks.

Why are you testing if j==j ??

Are you trying to do line plots or trying to do dot plots?

I want to plot each cell,{1x1 cell} {1x7 cell} {1x2 cell} only have similar color, i want different color

[k1,k2]=size(Z)

[1,3]

if j=1 {1x1 cell} if j=2 {1x7 cell} if j=3 {1x2 cell}

Okay, but why are you testing "if (j==j)" ? The only case in which a number is not equal to itself is if the number holds NaN.

When you plot each cell, are you wanting a line plot or a scatter plot?

Could you confirm that you only want to use exactly 3 values from each cell, rather than three columns or three rows ?

Z are cluster, i have three cluster if j=1 {1x1 cell} cluster if j=2 {1x7 cell} if j=3 {1x2 cell} i need line plot, i want to use 3 values from each cell

[Tomas]

i want each cluster differentiate different color

[Walter Roberson]

What should the three values be connected to? Should there be a different line for each "j", or should there just be one line total but the parts of it that come from different "j" should be in different colors?

[Tomas]

each j different color
