Hey Auryn_
Assuming random values for your variable “k” the code below explains how to plot in 3D using “surf”:
% Initialize the cell array
numMatrices = 10; % Number of matrices (cells)
numRows = 80; % Number of rows in each matrix
numCols = 31; % Number of columns in each matrix
% Create a cell array with random numbers
k = cell(1, numMatrices);
for i = 1:numMatrices
k{i} = rand(numRows, numCols); % Each cell contains an 80x31 matrix
end
% Define the x and y axes for the plot
x = 1:numRows; % X-axis
y = 1:numMatrices; % Y-axis (for each matrix in the cell array)
% Preallocate a matrix to hold the Z values
z = zeros(numRows, numMatrices);
% Calculate the mean of each row for each matrix
for i = 1:numMatrices
% Compute the mean across columns for each row
z(:, i) = mean(k{i}, 2); % Mean of each row
end
% Create the 3D surface plot
figure;
surf(x, y, z');
xlabel('X');
ylabel('Matrix Index (Y)');
zlabel('Mean Value (Z)');

Here is the documentation for “surf” for reference:
