can you help me, to modify the parameters of the axes in matlab R2014a

can you help me, to modify the parameters of the axes in matlab R2014a all these works are not taken into account in this version.

     ax = gca

     ax.XAxisLocation = 'top'

     ax.YAxisLocation = 'left'

     ax.XDir = 'normal'

     ax.ZDir = 'reverse'

     ax.DataAspectRatio = [1 1]  

     ax.PlotBoxAspectRatio = [1 1] 

     ax.PlotBoxAspectRatioMode='manual'

     ax.Position=[0 0 1 1]

     ax.ActivePositionProperty='position'_

I want to change:

• the Xaxes in top
• reverse the direction of the Y axis
• change position in [0 0 1 1]
• and modify ax.DataAspectRatio = [1 1]

In R2014a, you can use set() to modify the properties. For example to modify XAxisLocation use

set(ax, 'XAxisLocation', 'top');

you can modify all other properties with similar method.

thanks for your help , but this solution is not accepted and displays this error message

Have you run following line

ax = gca;

also, type

class(ax)

does it output: matlab.graphics.axis.Axes?

@manel: Then "ax" has been defined as a struct before. Search for anything like "ax.XDir...", where "ax" is overwritten by a struct.

     ax = gca
     set(ax, 'XAxisLocation', 'top', ...
             'YAxisLocation', 'left', ...
             'XDir', 'normal', ...
             'ZDir', 'reverse', ...
             'DataAspectRatio', [1 1], ...
             'PlotBoxAspectRatio', [1 1], ...
             'PlotBoxAspectRatioMode, 'manual', ...
             'Position', [0 0 1 1], ...
             'ActivePositionProperty, 'position');

This should work.

this answer is accepted I mean without error but actually nothing changes for the display ie nothing is applied to the typed configuration

What I want to do is draw with a plot a straight inclined with 20 degree (angle theta)and get the matrix that represents, it using:

     F = getframe;

     [X, map] = frame2im (F);

but for that I need to modify the axes of the plot to have the same unit for Xaxe and Yaxe and even to use as a unit the pixel
