Для всех, кто еще заинтересован, вот мое решение с использованием класса:
classdef progressbar < handle
properties(Access = protected)
h_panel % Panel on which everything sits
h_ax % The progress range axes
h_pbar % The bar representing progress (patch)
h_ptext % Percentage label
end
properties(Access = public, Dependent = true)
range % Progress range
pvalue % Current value
percent % Percentage complete (relative within range)
position % Position of the object (panel)
ax_tag % Tag of the axes
visible % Is the object (panel) visible?
end
properties(Constant = true)
default_color = [.75 .75 .9];
end
methods
% Initializer
function obj = progressbar(fig, pos, range)
if nargin < 3
range = [0 1];
end
obj.h_panel = uipanel('Parent', fig, 'Units', 'Inches', ...
'Position', pos, 'Tag', 'progbar_panel');
obj.h_ax = axes('Parent', obj.h_panel, ...
'Units', 'Inches', 'Position', [0 0 obj.position(3) obj.position(4)], ...
'XTickLabel', '', 'XTick', [], 'YTickLabel', '', 'YTick', []);
obj.h_pbar = patch([range(1) range(1) range(1) range(1)], [0 0 2 2], ...
obj.default_color, 'Parent', obj.h_ax, 'Tag', 'progbar_patch');
obj.h_ptext = text(obj.position(3)/2, obj.position(4)/2, '0%', ...
'Parent', obj.h_ax, 'FontWeight', 'bold', 'Units', 'Inches', ...
'HorizontalAlignment', 'center', 'Tag', 'progbar_text');
obj.range = range;
obj.ax_tag = 'progbar_ax';
end
% Property Access Methods
function set.range(obj, value)
% Instead of replotting, just reset the XLim to the
% extremities of the input range. If the values are not
% increasing, just default to [0 1].
if value(end) > value(1)

function value = get.range(obj)

end
function set.pvalue(obj, value)
% Expects a single value to represent progress value and
% constructs the selection rectangle from that. If multiple

end
function value = get.pvalue(obj)
% The progress bar is actually 2D, but we treat as if it is 1D.
% Hence the XData is actually an array of four values but we
% only consider the second (progress maximum).
limits = get(obj.h_pbar, 'XData');
value = limits(2);
end
function set.percent(obj, value)
% Expects a single value between 0 and 1.
limits = obj.range;
obj.pvalue = value * (limits(2) - limits(1)) + limits(1);
end
function value = get.percent(obj)
limits = obj.range;
value = (obj.pvalue - limits(1)) / (limits(2) - limits(1));
end
function set.position(obj, value)
set(obj.h_panel, 'Position', value);

function value = get.position(obj)
value = get(obj.h_panel, 'Position');
end
function set.ax_tag(obj, value)
set(obj.h_ax, 'Tag', value);
end
function value = get.ax_tag(obj)

end
function set.visible(obj, value)
if (isnumeric(value) && value >= 1) || strcmp(value, 'on') == 1 || strcmp(value, 'On') == 1
set(obj.h_panel, 'Visible', 'on');

end
end

end

function increment(obj)
% Don't use this if the range is less than 1.
obj.pvalue = obj.pvalue + 1;
end
function display_text(obj, text, color)

Объявить экземпляр следующим образом: pb = progressbar(gcf, [1 1], [0 20]);
Может использоваться с относительными или действительными числами, т.е. pb.pvalue = 10; и pb.percent = .5; делают то же самое в моем примере.
