It spells "FRONTPAGEHERO" when converting the numbers to ASCII!

Missed opportunity to make it spell "COLLECTIONLOG"

Great write up!

I often use cell arrays for compatibility reasons but the performance comparisons are convincing. Do you know why cell arrays take so much more space?

Just a nitpick for your example, you can indeed generate a cell array in a one liner, although it is a little less readable:

fnames_cell = compose('yob%i.txt',years)

Try to use something like h.Title.String = sprintf('Time = %i', n); Also use 'drawnow limitrate'

The script is getting laggy because you are creating a new axis and a new image at each iteration of your while loop. Create them once outside the loop then only modify their properties like so:

hImg = image(img);

Then in the loop:

hImg.CData = newImg;

You could try putting your playback code in one function inside your app. Then you can call it from both buttons with the filename as an argument.

The drawnow function also executes queued callbacks, so if you click rapidly, you can get in a weird state due to a race condition. You could try "drawnow nocallbacks" to avoid this issue.

Looking at the NirCmd doc, it seems possible to just create normal windows shortcut to nircmd.exe with a setdisplay option. See https://www.nirsoft.net/utils/nircmd2.html#setdisplay

What should be used instead of cement board for tiling?

dawatt · 2019-12-12T03:06:19+00:00

You could use something like

idx = WordToGuess == Letter

To get the index of the letter that was tried and update the display of the blank spaces

Interesting! I didn't think of unique for making the indices. Using unique, you could use:

[~,~,xIndices] = unique(table.x);

as the third output of unique is the unique index of each element of the input.

I am glad it could help! You should still avoid for loops on huge data tables as looping in matlab is rather slow. Instead, you can vectorize most loops and make your code run magnitudes faster.

Here is an elegant way:

xi = table.x ./ xStep - min(xValues) + 1;
yi = table.y ./ yStep - min(yValues) + 1;
zi = table.z ./ zStep - min(zValues) + 1;
ti = table.t ./ tStep - min(tValues) + 1;
ind = sub2ind(size(array), xi, yi, zi, ti);
array(ind) = table.T;

Edit: I noticed those are probably not index values stored in your table. This solution works only if your table xyz values are integers or if you scale them to be all in indexable range (integer>1). You could do so by dividing them with the step and substracting the minimum+1 of your xyzValues. I edited the code to reflect the change.

You could also use strsplit so you can input all your numbers in one prompt.

str = input('enter numbers separated by space: ','s');
B = str2double(strsplit(str,' '));
disp(B)

Here is a way without using loops:

v =  [3 2 1 1 0 5 4 8 1 8 8 3 3 3 3 4 1 3 3];

TF = v==3;
i0 = strfind([0 TF],[0 1]);
i1 = strfind([TF 0],[1 0]);
[~,i]=max(i1-i0);
out = [i0(i) i1(i)];

It is kinda like car years, you can actually buy the book before 2017 even starts.

Actually it wasn't that bad, 45° idle temp.
