can i implement mti on range doppler map by zeroing the velocity axis near zero?

Not sure what that means. Explain "zeroing the velocity axis near zero".
You can certainly plot a symbol at a certain (x,y) point like this:
hPlot = plot(x, y, 'r+', 'LineWidth', 2, 'MarkerSize', 30);
and then to remove it in preparation for plotting the next point:
delete(hPlot);

in the array of data that contains velocity components in rows by making the values of that particular row (the values that contain the velocity compnents near zero) to zero as shown in image

I still don't understand. How many components are there? There would be 3 if the object is moving in 3 dimensions, and 2 if it's moving in 2-D and 1 if it's moving along a line. You seem to have hundreds of velocity components. Why? If your object moving in a hundred dimensional space?
If you want to zero out a row in a matrix, do this
velocity(rowNumber, :) = 0;
If you want to zero out a column in a matrix, do this
velocity(:, columnNumber) = 0;
