If you know the line number, then at the command line you can. Theme. Copy. dbstop in FILENAME at LINENUMBER. But inside the editor it is easier just to click on the dash that shows up just to the right of the line number and before the code itself. A single click will turn it red, indicating that a breakpoint is there.Ending vector value, specified as a real numeric scalar. k is the last value in the vector only when the increment lines up to exactly land on k.For example, the vector 0:5 includes 5 as the last value, but 0:0.3:1 does not include the value 1 as the last value since the increment does not line up with the endpoint.Line width, specified as a positive value in points, where 1 point = 1/72 of an inch. If the line has markers, then the line width also affects the marker edges. The line width cannot be thinner than the width of a pixel.Create a newline character. Then use + to concatenate the newline character and more text onto the end of a string. str = "In Xanadu did Kubla Khan" ; str = str + newline + "A stately pleasure-dome decree". str = "In Xanadu did Kubla Khan A stately pleasure-dome decree". Although str displays on two lines, str is a 1-by-1 string. Line style and color, specified as a character vector or string scalar containing characters and symbols. The characters and symbols can appear in any order. You can specify the line style, line color, or both. Marker symbols such as 'o' are ignored. Example: '--g' is a green dashed line.If you want the line to have specific end points, you can use the line function. For example, this code draws a horizontal line at y = 5 between the points x = -6 and x = -2. Theme. Copy. y = 5; line ( [-6,-2], [y,y]) Starting in R2018b, you can use the xline and yline functions to draw vertical and horizontal lines, respectively. For example ...Line Properties. Chart line appearance and behavior. expand all in page. Line properties control the appearance and behavior of a Line object. By changing property values, you can modify certain aspects of the line chart. Use dot notation to query and set properties. p = plot (1:10); c = p.Color; p.Color = 'red';Create a new matrix containing the RGB triplets for red, green, and blue. Then set the ColorOrder property to that matrix. The plot updates immediately with the new colors. mycolors = [1 0 0; 0 1 0; 0 0 1]; ax = gca; ax.ColorOrder = mycolors; MATLAB also cycles through different line styles in addition to colors.3 Answers Sorted by: 4 MATLAB's plotting works on a point-by-point basis from the vectors you give.
