m2xdate

MATLAB^® serial date number to Excel^® serial date number

Syntax

DateNum = m2xdate(MATLABDateNumber, Convention)

Arguments

MATLABDateNumber

A vector or scalar of MATLAB serial date numbers.

Convention

(Optional) Excel date system. A vector or scalar. When Convention = 0 (default), the Excel 1900 date system is in effect. When Convention = 1, the Excel 1904 date system in used.

In the Excel 1900 date system, the Excel serial date number 1 corresponds to January 1, 1900 A.D. In the Excel 1904 date system, date number 0 is January 1, 1904 A.D.

Due to a software limitation in Excel software, the year 1900 is considered a leap year. As a result, all DATEVALUE's reported by Excel software between Jan. 1, 1900 and Feb. 28, 1900 (inclusive) differs from the values reported by 1. For example:

In Excel software, Jan. 1, 1900 = 1
In MATLAB, Jan. 1, 1900 = 2

Vector arguments must have consistent dimensions.

Description

DateNum = m2xdate(MATLABDateNumber, Convention) converts MATLAB serial date numbers to Excel serial date numbers. MATLAB date numbers start with 1 = January 1, 0000 A.D., hence there is a difference of 693961 relative to the 1900 date system, or 695422 relative to the 1904 date system. This function is useful with Spreadsheet Link™ EX software.

Examples

Given MATLAB date numbers for Christmas 2001 through 2004

DateNum = datenum(2001:2004, 12, 25)

DateNum =

      731210      731575      731940      732306

convert them to Excel date numbers in the 1904 system

ExDate = m2xdate(DateNum, 1)

ExDate =

       35788       36153       36518       36884

or the 1900 system

ExDate = m2xdate(DateNum)

ExDate =

       37250       37615       37980       38346
