Formatting the color/font of a Cellplot using code

Hello,

I have written a code that randomly places a specific number of symbols in a 4x4 matrix and fills the rest of the cells with *'s. I want a code that can save this matrix (or cell array) as a figure that is a white background with only black numbers or stars. I was able to use the cellplot function to make a figure of the cell array. However, I cannot find any information on code that can change the physical appearance of the cellplot. If you plot it you can see that the numbers appear in colourful squares. It is possible to do this manually using the figure properties GUI, however I need to make thousands of these matrices and therefore would like to automatize making, saving and naming the figure. I have copied and pasted my code below. Any help on this would be greatly appreciated!

n = 4
p = 2
A = repmat('*', 4, 4)
rp = randperm(4*4)
A(rp(1:p))= num2str(n)
A1 = num2cell(A)
cellplot(A1)

you can generate multiple figures placing the command figure with the numeral differentiating each figure window. For instance:

n = 4
p = 2
A = repmat('*', 4, 4)
rp = randperm(4*4)
A(rp(1:p))= num2str(n)
A1 = num2cell(A)
figure(1);cellplot(A1)
title('figure 01')
save(file_A1.mat,'A1')

rp = randperm(4*4)
A(rp(1:p))= num2str(n)
A1 = num2cell(A)
figure(2);cellplot(A1)
title('figure 02')
save(file_A2.mat,'A1')

different figures and different .mat files saving each cell.

You can also save the entire workspace with simply

save(file1.mat)

Load .mat files with

load('file_name.mat')

Or direct 'casting' line by line:

fid2=fopen('example_text2.txt','w')

for k=1:1:length(A)
  B0=A1(k,1)
  fwrite(fid2,B0,'char')
end
fclose all

Repeat for each cell. To automate many cells generation and storage, first put all the file names, and figure titles in separate lists and the automate with a for loop, feeding figure(k)l .. and for each file name.

Hi John, Thank you, this is very helpful for saving the data! I am wondering if you know how to generate code to manually edit the color, size, end edge color of the plot?

Thanks again!

with

colormap autumn

the default colour map for surf is parula, haven't checked for cellplot, or

    colormap jet

or defining your custom colormap

saturated colours are

Color  RGB Triplet
yellow  [1,1,0]
magenta  [1,0,1]
cyan  [0,1,1]
red  [1,0,0]
green  [0,1,0]
blue  [0,0,1]
white  [1,1,1]
black  [0,0,0]

reduce the values to zero for dark, any real positive value between [0 1] are accepted.

an example of custom colormap would be for instance:

map1 = [0.2, 0.1, 0.5
    0.1, 0.5, 0.8
    0.2, 0.7, 0.6
    0.8, 0.7, 0.3
    0.9, 1, 0];

applied to

colormap(map1)
