你不需要activeX，matlab有内置函数，xlswrite和xlsread：

帮助文件：

xlswrite(filename,A) writes array A to the first worksheet in Excel

file filename, starting at cell A1.

xlswrite(filename,A,sheet) writes to the specified worksheet.

xlswrite(filename,A,range) writes to the rectangular region specified

by range in the first worksheet of the file. Specify range using the

syntax 'C1:C2', where C1 and C2 are two opposing corners that define

the region.

xlswrite(filename,A,sheet,range) writes to the specified sheet and

range.

status = xlswrite(filename,A,sheet,range) returns the completion

status of the write operation: true (logical 1) for success, false

(logical 0) for failure. Inputs sheet and range are optional.

[status,msg] = xlswrite(filename,A,sheet,range) returns any warning or

error message generated by the write operation in structure message.

Inputs sheet and range are optional.

和：

[num,txt,raw] = xlsread(filename) reads data from the first worksheet

in the Microsoft Excel spreadsheet file named filename and returns the

numeric data in array num. Optionally, returns the text fields in cell

array txt, and the unprocessed data (numbers and text) in cell array

raw. If your system does not have Excel for Windows, xlsread operates

in basic import mode, and reads only XLS or XLSX files.

[num,txt,raw] = xlsread(filename,sheet) reads the specified worksheet.

[num,txt,raw] = xlsread(filename,range) reads data from the specified

range of the first worksheet in the file. Specify range using the

syntax 'C1:C2', where C1 and C2 are two opposing corners that define

the region.

[num,txt,raw] = xlsread(filename,sheet,range) reads from the specified

sheet and range.

[num,txt,raw] = xlsread(filename,-1) opens an Excel window to

interactively select data. Supported only on Windows systems with

Excel software.

[num,txt,raw] = xlsread(filename,sheet,range,'basic') reads data from

the spreadsheet in basic mode, the default on systems without Excel

for Windows.

[num,txt,raw,custom] = xlsread(filename,sheet,range,'',functionHandle)

reads from the spreadsheet, executes the function associated with

functionHandle on the data, and returns the final results. Optionally,

returns additional custom output, which is the second output from the

function. xlsread does not change the data stored in the spreadsheet.

Supported only on Windows systems with Excel software.
