all elements of the resulting matrix are given the data type of the Answered: bio lim on 21 Jul 2015 Accepted Answer: bio lim. All numeric types support basic array operations, such as indexing,

To store data as an integer, you need to convert from double to the desired integer type.

binary literals are stored as integers.

After that, the difference between adjacent representable double precision numbers becomes more than 1. Convert pi and 1/3 from variable-precision form to double precision. your data, you can save memory and program execution time.This example shows how to perform arithmetic on integer data representing signals and images.Create complex numbers.

Being able to address elements in such structures with indices other than double is key. Integer and single precision arrays offer more memory-efficient storage than double precision.

I ama also trying to use mRMR and getting the same errors.

If you really have an integer type and need to convert it to double type, use the double function. arguments of type 'int64'.

Complex numbers consist of a real part and an imaginary Featured on Meta I am using MATLAB to load a text file that I want to make a sparse matrix out of. I need to convert my matrix [648x2400 double] into integers value to use a mRMR function, but I do not know how to do that. To convert an array of type “double” to an integer type, you can use a function such as “int64”, which converts the input to a 64-bit integer.

How can I convert a variable whose value is double to integer or to float? Other MathWorks country sites are not optimized for visits from your location.How can I convert a variable whose value is double to integer or to float? Rounding type, specified as 'decimals' or 'significant'.The rounding type determines whether round considers digits in relation to the decimal point or the overall number of significant digits.N must be a positive integer when you specify 'significant'.In that case, the round function rounds to the nearest number with N significant digits..

Error in ==> make_network at 5graph =sparse(int64(listedges(:,1)),int64(listedges(:,2)),ones(size(listedges,1),1)); How can I convert the text file entries loaded as double so as to be used by the There is no need for any conversion, keep the indices There are two reasons why one might want to convert to If you want to convert because of the first reason - then there's no need to: Matlab works with There is another very good reason ( and really the primary one..) why one may want to convert indices of any structure (array, matrix, etc.) the empty matrices are ignored in the resulting matrix.These examples show how to concatenate different data One major issue with Matlab is the inability to more finely control the size of multidimensional structures in this way. - ... Hallo, ich versuche mich gerade an der Funktion "streamline" und habe folgendes Problem: Web browsers do not support MATLAB commands.Choose a web site to get translated content where available and see local events and offers. I have tried to convert by uint8(matrix) or int8(matrix) but it does not give integers... And I always have this note: "Undefined function 'mrmr_mid_d' for input arguments of type 'int8' " (or double, or uint, and so on) can someone help me? your coworkers to find and share information. Do you mean that:The error message you report ("Undefined function 'mrmr_mid_d' for input arguments of type 'int8' ") just sounds like MATLAB cannot recognize the function, mrmr_mid_d.m.You need to add the folder containing that function to the MATLAB path.

By default, MATLAB stores all numeric values as double-precision floating point. Thank you for your prompt answer anyway!Hi Emilie, I am facing the same problem.
