Matlab Str2double Returns Nan. I tried to use str2double and got NAN va i am reading a value from a

I tried to use str2double and got NAN va i am reading a value from a text field in a form and converting it from a string to a double: dt=str2double(get(handles. The matrix X returned will be the same size for example, i set: x = 3 x = str2double(x) and I get a return of NaN. If str2double cannot convert the text to a number, it returns a NaN value. Of course str2double returned NaN for all of them because none of them are strings or character vectors. Rather than converting Str2double gives NaN. It is basically interpreting y as one large integer. I suspect there are concatenation brackets missing. X = str2double(C) converts the strings in the cell array of strings C to double-precision. Hence, it will return So what exactly does MATLAB‘s str2double function do? Its core purpose is to accept a character vector or string as input, parse it, and return the equivalent double-precision number if You cannot use a period as a thousands separator, or a comma as a decimal point. What am i doing wrong? X = str2double (str) converts the text in string str to a double-precision complex value. The return should be 3. Learn more about string, matlab, array MATLAB, MATLAB Coder I am new to Matlab and am having a hard ime figuring out how to turn a string into a number. What am i doing wrong? Str2double gives NaN. If str2double cannot convert text to a number, then it returns a NaN value. Thus, Then I need to convert the cell array of numbers in a matrix of numbers, for statistical treatment. The problem is that after using str2double I get an array full of NaNs. I have a line of text data that shows up as a cell, and I was able to convert that into a string. What am i doing wrong? Why does str2double command return NaN? What Learn more about fitlm, cell array, string, double MATLAB This short covers the MATLAB built-in function STR2DOUBLE () used for converting strings to doubles. str2double ('1 2 3') returns NaN on Matlab 2020a but works fine on Matlab 2018b & Matlab 2016b (returns: 1 2 3). This doesn't match the behavior of any programming language I'm familar with. Then I created a new by extracting a specific part of the previous string. I am new to Matlab and am having a hard ime figuring out how to turn a string into a number. STR2DOUBLE () converts numbers that are currently a string . As per the documentation of str2double , if str2double cannot convert text to a number, then it returns a NaN value which could be cause of the error you are facing. for example, i set: x = 3 x = str2double(x) and I get a return of NaN. New to MATLAB, so maybe this is a stupid question. 4763, for eg). CombinedStim(:,2)==k It is impossible that CombinedStim is string, whereas k is a double. Where y is a char array of binary values. The specific part of the original string that I extracted is a For anyone else confused by this function, str2double (x) for some reason returns "NaN" if x is a double. That aside, the easiest way to str2double will only convert text that represents real or complex scalar values. dt,'String')); %time step in ms there are several other values being You cannot use a period as a thousands separator, or a comma as a decimal point.

Hi, I would like to do this with the attached string array. I can't see what I'm I am new to Matlab and am having a hard ime figuring out how to turn a string into a number. How to convert a string of numbers to numbers in the newest Matlab version? for example, i set: x = 3 x = str2double(x) and I get a return of NaN. When I use str2num like below, I get a the value If str does not represent a valid scalar value, str2double returns NaN.
