MATLAB: Converting cell values from standard form

arrayconversionMATLABscientific notationstandard form

I did some multiplication/division with cell values in an array. The output is entered into the array as standard form.

array = [3.7505e+03 , 7.2224e+03] and so on

How can I change the notation to the following:

array = [37505 , 72224]

MATLAB: How to convert the scientific notation to standard form

If you are using R2014b or newer then I understand there are new facilities to control this.

For R2014a or earlier, you need to set the axes YTickLabel property yourself. For example,

curYTick = get(gca,'YTick');
YLabel = cellstr( num2str( curTick(:), '%f') );
set(gca, 'YTickLabel', YLabel);

Adjust the %f format code as needed.

MATLAB: How to extract the first part of a number in standard form/scientific notation

One of many ways to do this is to:

1. Convert the number into a scientific notation string

2. Split the string using 'e' as the delimiter

3. Convert the first element of the resulting array from the split to a double.

x = 346346346^2; % Create some big number
string = sprintf('%.2e', x); % Convert number to a scientific notation string with 2 decimal places of precision
stringParts = strsplit(string,'e'); % Split the string where 'e' is
firstPart = str2double(stringParts(1)); % Get the 1st part of stringParts which is the first part of standard form.
