To transform the matrix "B", so that all values from the first negative value onwards in each row are set to zero, you can loop through each row, find the first negative value using the "find" function, and set that value and all subsequent values in the row to zero.
Here's how you can do it:
B = [
0.0374 0.0216 0.0185 -0.0320 -0.0012 0.0000 0.0063;
0.0311 0.0157 0.0177 -0.0364 0.0029 -0.0022 0.0057;
0.0244 0.0093 0.0170 -0.0400 -0.0044 -0.0044 0.0050;
0.0178 0.0027 0.0164 -0.0428 -0.0056 -0.0065 0.0042;
0.0114 -0.0039 0.0160 -0.0448 -0.0064 -0.0084 0.0034
];
% Loop through each row
for i = 1:size(B, 1)
% Find the index of the first negative value
first_neg_idx = find(B(i, :) < 0, 1);
% If a negative value is found, set it and all subsequent values to zero
if ~isempty(first_neg_idx)
B(i, first_neg_idx:end) = 0;
end
end
disp(B);
