Question

我想保存通过3D矩阵中的GUI按钮输入的矩阵。例如：我点击按钮1，将2-2矩阵放入3D矩阵的第一个切片中。我点击按钮3，并在第二个切片中放入不同的2-2矩阵。等等等等。我希望这很清楚。我遇到的问题是我不是一个经验丰富的程序员。我目前在开放函数中初始化一个零矩阵：

storageMatrix  = ones(2,2,100);
setappdata(0, 'storageMatrix', storageMatrix);

我在这个主脚本中放了一个函数updateStorageMatrix，请注意，这还没有完成。

function updateStorageMatrix

storageMatrix = getappdata(0, 'storageMatrix');

而且当我查看我的按钮1代码时，它看起来像这样：

% --- Executes on button press in Add_Straightduct.
function Add_Straightduct_Callback(hObject, eventdata, handles)
%prompt command for k number and length
    prompt       = {'k0:','Length:'};
    dlg_title    = 'Straight Duct specs';
    num_lines    = 1;
    SDelements   = {'0','0'};
    Straightduct = inputdlg(prompt,dlg_title,num_lines,SDelements)

%insert values in function
    sizeStorageMatrix = size(getappdata(0,'storageMatrix'));      %get size of the storage matrix

    dimT              = sizeStorageMatrix(1,3);   %take the number of matrices

        if dimT==1

            straightDuct = straight_duct(str2num(SDelements{1}), str2num(SDelements{2}), Mach_Frange(1,1))

            setappdata(handles.updateStorageMatrix,'storageMatrix', storageMatrix(1:2, 1:2, 1))=straight_duct(str2num(SDelements{1}), str2num(answer{2}), Mach_Frange(1,1))

            dimT+1

        else 
            setappdata(0,'storageMatrix', storageMatrix(1:2, 1:2, dimT+1))=straight_duct(str2num(SDelements{1}), str2num(answer{2}), Mach_Frange(1,1))
            dimT+1
        end

straight_duct()是我在计算消声器时在脚本中使用的函数，我有几个这样的函数，我不确定这是否是使用GUI时的工作方式。我希望你能理解我想要实现的目标，并在我的路上帮助我。所以我实际上可以为我的脚本创建一个UI：）

这假设你已经在GUI中的其他地方初始化了storageMatrix ......

handles.storageMatrix = zeros(2,2,100);
guidata(hObject,handles); % Must call this to save handles so other callbacks can access the new element "storageMatrix"

然后在你的第一个按钮的回调...

% --- Executes on button press in Add_Straightduct.
function Add_Straightduct_Callback(hObject, eventdata, handles)
.
. % Whatever initializations you need to do
.

localStorageMatrix = handles.storageMatrix;  %load the storageMatrix being used by other callbacks/functions

.
. % Whatever you need to do to generate the new 2x2 matrix "slice"
.

localStorageMatrix(:,:,end+1) = newSlice; % appends the new slice to the end of the, indexing using colons assumes newSlice is of the same first and second dimension as other slices in localStorageMatrix
handles.storageMatrix = localStorageMatrix; % overwrite the storageMatrix in handles with the contents of the new localStorageMatrix
guidata(hObject,handles); % save the handles struct again now that you've changed it

或者，您可以在整个过程中使用handles.storageMatrix，但不包括localStorageMatrix，但我已将其包含在内以供强调。
