从uigetfile检索文本字符串？

Question

'Afternoon all， 我一直在将数据加载到脚本中，并且希望将文件名称作为图形的标题（或者只是在可见的文本中）。 我无法弄清楚，任何建议表示赞赏.... 我运行代码：

%% File selection 

[fileName, pathName] = uigetfile({'*_SUMMARY.mat' 'MAT-files (*_SUMMARY.mat)'}, 'Load Data', '.'); 
if pathName == 0, error('No file selected'), end 
load(fullfile(pathName,fileName)) 
%% Intercept and gradient 
%-------c---------m------] 
FR = [0.6051, -1.9666e-05;... % zero 
    0.60429, -1.8295e-05;... % 60 
    0.60576, -2.1043e-05;... % 120 
    0.60311, -1.5683e-05];  % 180 
N = numel(FR(:,1)); 
% x-axis limits 
x = linspace(1,1000,N)'; % Vector of [N] equally spaced points in range 0:1000 
% End position as scalar value 
idx = 102; % Get data for sheet 102 
V = 1:numel(SheetInkThickness(1,:)); % vector for 'x' values 
FinalSheetSum = sum(SheetInkThickness(idx,:)); % sum 
average = mean(SheetInkThickness(idx,:)); % mean 
ActMinusAve = (SheetInkThickness(idx,:)-average).^2; % (Act-Ave).^2 
sumActMinusAve = sum(ActMinusAve); % Sum of Act-Ave 
SheetInkProperties = [V', (SheetInkThickness(idx,:))', ActMinusAve']; % matrix for storing ink sheet properties 
[maxActMinusAve, idmaxActMinusAve] = max(ActMinusAve); % max of ActMinusAve 
[minActMinusAve, idminActMinusAve] = min(ActMinusAve); % min of ActMinusAve 
[maxSIT, idmaxSIT] = max(SheetInkThickness(idx,:)); 
[minSIT, idminSIT] = min(SheetInkThickness(idx,:)); 
[maxSIT2, idmaxSIT2] = max(ActMinusAve); 
[minSIT2, idminSIT2] = min(ActMinusAve); 
[p, S] = polyfit(V', SheetInkProperties(:,2),1); 
[y,delta] = polyval(p,V',S); 
StDev = std(SheetInkThickness(idx,:)); 
diff1 = (maxSIT-average); % Difference between max and average 
diff2 = (average-minSIT); % Difference between min and average 
if diff1>diff2;  % Find which difference is greater 
    difference = diff1; 
else difference = diff2; 
end 
%% Sheet ink thickness 
fh5 = figure(5); 
clf 
hold on 
grid on 
subplot(2,2,3:4) 
plot(V, ActMinusAve, 'b.-'); 
text(0.45, 0.9, ['maximum: ', num2str(maxSIT2)],... 
    'units','normalized') 
text(0.45, 0.85, ['minimum: ', num2str(minSIT2)],... 
    'units','normalized') 
text(0.45, 0.8, ['System length:  ', num2str(Sum.Total_Length),' (mm)'],... 
    'units','normalized') 
text(0.45, 0.75, ['Number of rollers: ', num2str(Sum.NoOfRollers+1)],... 
    'units','normalized') 
text(0.45, 0.7, ['Number of nips: ', num2str(Sum.NoOfNips)],... 
    'units','normalized') 
text(0.9, 0.85, {'{\it\Sigma(x-{\itxmean)^2} = }',... 
    num2str(sumActMinusAve)},'units','normalized'); 
title('{\it(x-{\itxmean)^2}}'); 
xlabel('segments on sheet'); 
ylabel('ink thickness'); 
% Lower figure 
subplot(2,2,1:2) 
plot(V, SheetInkThickness(idx,:)) 
hold on 
plot(V, average,'r-'); 
text(V(1,end),average,'average'); 
text(0.45, 0.9, ['average:  ', num2str(average)],... 
    'units','normalized') 
text(0.45, 0.85, ['difference: ', num2str(difference)],... 
    'units','normalized') 
text(0.45, 0.8, ['Standard deviation: ', num2str(StDev)],... 
    'units','normalized') 
text(idmaxSIT, maxSIT, ['\leftarrow max = ',num2str(maxSIT)]); 
text(idminSIT, minSIT, ['\leftarrow min = ',num2str(minSIT)]); 
title('sheet ink thickness') 
xlabel('sheet length (segments)'); 
ylabel('ink thickness (um)'); 

是啊，我知道这是混乱的，肯定有机会到循环/ vectorise一些这方面的代码但这是一项正在进行的工作。 任何人都可以指出我正确的方向来解决我的问题吗？ 感谢 理查德

如果我理解你的要求，你可能想看看使用mfilename

http://www.mathworks.com/help/matlab/ref/mfilename.html

因此，举例来说，如果你想使用的文件名作为数字题，你可以使用

% File is named myScript.m 
figure 
axes 
title(mfilename) 

如果你想了解更多细节，请告诉我
