用matlab修改过的心电数据，用分隔符隔开每个数据，64位双精度，可作为现成的心电信号发生数据-Matlab modified with ECG data, each with a delimiter separated data, 64-bit double precision, can occur as a ready-made ECG data

在超声相控阵成像中，处理回波信号成像时需要插值和坐标转换，此程序时针对64位win7系统生成的mex文件。-Ultrasonic phased array imaging processing the echo signal imaging interpolation and coordinate transformation, this program is for 64-bit win7 system generated mex file.
