MATLAB: How to run an entire M-file without adding it to the path, in MATLAB 8.0 (R2012b)

MATLAB

I want to directly run an M-file with several sections that I have opened in the Editor.

I would like the functionality of the "Evaluate entire file" option which was available in previous releases.

Best Answer

The "Evaluate entire file" option is not available in the Toolstrip.

A workaround would be to create a shortcut with the following code :

activeEditor = matlab.desktop.editor.getActive;
eval(activeEditor.Text);

This code creates an object of class matlab.desktop.editor which has the property 'Text' that contains all the text included in the active file of the Editor. By using 'eval(activeEditor,Text)' you are evaluating all the commands included in the file.

MATLAB: How to override the zoom uicontextmenu with a custom uicontextmenu, when in zoom mode, in MATLAB 7.3 (R2006b)

This can be accomplished with the zoom accessor object. The following example illustartes how this can be done:

% Define the context menu
cmenu = uicontextmenu;
% Define the line and associate it with the context menu
hline = plot(1:10,'UIContextMenu', cmenu);
% Define callbacks for context menu items
cb1 = ['set(hline, ''LineStyle'', ''--'')'];
cb2 = ['set(hline, ''LineStyle'', '':'')'];
cb3 = ['set(hline, ''LineStyle'', ''-'')'];
% Define the context menu items
item1 = uimenu(cmenu, 'Label', 'dashed', 'Callback', cb1);
item2 = uimenu(cmenu, 'Label', 'dotted', 'Callback', cb2);
item3 = uimenu(cmenu, 'Label', 'solid', 'Callback', cb3);
% Get the handle to the zoom mode object for the figure
zh = zoom(gcf);
% Set the UI Context Menu to the custom menu
set(zh, 'uicontextmenu', cmenu)

MATLAB: M-file function

Your function is calling itself without approaching any convergance or something that will allow it to end. Therefore it will run forever and eventually out of memory (hence the error). Try splitting it up into a script and a function as so:

Script:

 %creating window of plot from -5 to 50 using stepsize 0.25 for t x-axis
 %t should be on the x axis, v should be on the y axis
 k=0; 
for i= -5:.25:50
    k = k+1;
    t(k)=i;
    v(k)=vPieceWise(t(k));
end 
plot(t,v);
 
figure
plot(t,v);
hold on

Function:

%Part A: Mfile function to compute v as a function of t
function v = vPieceWise(t)
 if (t < 0)
        v = 0;
    elseif (0 <= t)&&(8<=16)
        v = -5*t+10*t.^2;
    elseif (8<=16)&&(t<=16)
        v = 624 - 3*t;
    elseif (t<=16)&&(t<=26)
        v = 12*(t-16).^2+36*t;
    elseif (26<t)
        v = 2136*exp(-0.1*(t-26));
 end
