How to replace number with string in a matrix
显示 更早的评论
I want to print like:
A =
1 1 1 1 1
1 1 1 1 1
1 1 Ali 1 1
1 1 1 1 1
1 1 1 1 1
but there are errors in my code:
for i = 1:5
for j = 1:5
A(i,j) = 1;
end
end
A

Agreed. All data in a variable must be of the same data type. The exception is a cell array, but that is because each cell is treated as a separate variable.
Your other option is to make all values strings.
A = string(ones(5));
A(3,3) = "Ali"

Hello,
The below code is working in Matlab but I am unable to execute this same thing in Matlab app designer.
fig = figure('Interruptible', 'off');
ax1 = subplot(1,2,1);
ax2 = subplot(1,2,2);
fig.WindowButtonMotionFcn = @(~,~) [];
t = timer('Period', 0.1, 'ExecutionMode', 'fixedRate', 'TimerFcn', {@mouseMotionCB, ax1, ax2});
start(t)
ginput(1)
stop(t);
delete(t);
function mouseMotionCB(fig, event, ax1, ax2)
currentPoint1 = ax1.CurrentPoint(1,1:3);
x1 = currentPoint1(1);
y1 = currentPoint1(2);
if (ax1.XLim(1)<x1)&&(x1<ax1.XLim(2)) && (ax1.YLim(1)<y1)&&(y1<ax1.YLim(2))
fprintf('This is axes 1, Current Point is %f %f %f\n', currentPoint1);
end
currentPoint2 = ax2.CurrentPoint(1,1:3);
x2 = currentPoint2(1);
y2 = currentPoint2(2);
if (ax2.XLim(1)<x2)&&(x2<ax2.XLim(2)) && (ax2.YLim(1)<y2)&&(y2<ax2.YLim(2))
fprintf('This is axes 2, Current Point is %f %f %f\n', currentPoint2);
end
end
Can anyone help me with this?

@Lavanya - I suggest that you remove this comment and create a new question as it doesn't seem to relate to the question posed by @Ali Raza. Also, has all of this code been put into your app, or just the relevant pieces? I would expect that your app (build from App Designer) would have the axes that you need to draw to...and so you wouldn't need the code to create a figure, add the subplots, etc....unless you want them to appear outside of the app.

Here is the ''app1.mlapp'' file. This '.mlapp' file should work same as above the code. But its not working. Can you help me with this?
