getting a number from a text file

I have txt file with 1 number inside only, nothing else.

is there a way to get that number as a variable so that i can use an if statement on it, more specifically if an inputted number is greater than the number in the txt file.

Ok thank you, reading it as a matrix worked. But now is there a way for me to have the code change the number in that file after an action.

Hint to OP: Always read the "See Also" section of the documentation

I did read this, but what i need to do is edit the number i have in the text file, so what i did is:

C

R=readmatrix('CashReserve.txt');

"CashReserve" is the name of the txt file.

And what i need to do is be able to update this txt file (CR) after an action.

so is there a way to do that in code

This just keeps getting more strange !

See: I'm using textscan to read in a csv file, but when I check the variable its incorrect

See: how to use ismember() to check if an inputted number exists in a matrix.

And keep watching for more yet to come!

filename = 'CashReserve.txt');
R = readmatrix(filename);
R = R - 1234.56;
writematrix(R, filename);
