MATLAB: How to default an array to show either 0’s or 1’s

arrayimage processingmatrix arraymatrix manipulation

I have an array that is defined by:

pict(i, j) = pict(i, j) + (sum1^2 - sum2)/32;

The array is a 41 x 41 double, and yields the result:

I'm plotting this figure using:

image(Rx, (Ry-40), pict, 'CDataMapping', 'scaled')

The area (in yellow) at -11 on the y-axis is my maximum point in the image. Is there a way for me to manipulate my array to make a range of maximum values 1 and everything else 0?

If I understood correctly,

wantedarray = pict >= 16.5;  %everything above 16.5 becomes 1, everything else 0
%or
wantedarray = double(pict >= 16.5);  %if an array of double instead of logical is required

Not sure I understand. You asked this before in this question and I answered it and you accepted. If it's how to get a gray scale image regardless if it's color or grayscale to start with you use this code:

temp = imread([path file(i).name])'
[rows, columns, numberOfColorChannels] = size(temp);
if numberOfColorChannels > 1
  temp2 = rgb2gray (temp); % Need to convert RGB to gray
else
  temp2 = temp; % It's already gray scale.
end

MATLAB: Optimal number of points to plot a sphere

Calculate the linear distance in pixel-widths between the center of the sphere and the edge. Using that as a radius, calculate the surface area in pixels. If you have more points than that surface area, you can prune back and still have full graphic representation at that drawing scale.

You can probably prune even further than that, but the calculation gets more difficult.
