fault offset model.jpg

Please urgently if possible I need to solve the following problem

An equation give me graph of some layers at depths z1, z2, z3, and z4 (see attached figure), and I need to break them down (vertical offset) with a constant = z2-z1= z3-z2=z4-z3 (if satisfying this condition), in addition to drowing a vertical line (red line in satisfied location)

在 MATLAB Online 中打开

Try something like this —

zv = sort(rand(4,1)) % Define 'z' Values

zv = 4×1

0.0231 0.1089 0.3493 0.7581

const = rand % Define Constant Offset

const = 0.0537

figure

plot([0 1], zv*[1 1], '-k', 'LineWidth',1.5)

hold on

plot([1 2], (zv-const)*[1 1], '-k', 'LineWidth',1.5)

hold off

xline(1, '-r', 'LineWidth',2)

linelabels = compose('z%d',numel(zv):-1:1);

text(zeros(size(zv)), zv, linelabels, 'Horiz','left', 'Vert','bottom')

text(zeros(size(zv))+2, zv-const, linelabels, 'Horiz','right', 'Vert','bottom')

set(gca, 'Visible','off') % Hide Axes (Optional)

Define the the ‘zv’ vector as a column vector of increasing values, and define the constant (‘const’) as a single scalar.

Try xline and yline. You can use the 'LineWidth' and 'Color' option to set up the line thickness and color.

What about the vetical offset?

Image Analyst 2022-9-30

If the line is not going all the way across the graph, you can use line or plot() to specify the endpoints at whatever x and y values you want, so you'll get line segments.
